Offered by Rice University. The ability to understand and apply Business Statistics is becoming increasingly important in the industry. A good understanding of Business Statistics is a requirement to make correct and relevant interpretations of data. Lack of knowledge could lead to erroneous decisions which could potentially have negative consequences for a firm. This course is designed to introduce you to Business Statistics. We begin with the notion of descriptive statistics, which is summarizing data using a few numbers. Different categories of descriptive measures are introduced and discussed along with the Excel functions to calculate them. The notion of probability or uncertainty is introduced along with the concept of a sample and population data using relevant business examples. This leads us to various statistical distributions along with their Excel functions which are then used to model or approximate business processes. You get to apply these descriptive measures of data and various

Abstract. This paper provides an introductory overview of a portion of distribution theory which is currently under intense development. The starting point of this topic has been the so-called skew-normal distribution, but the connected area is becoming increasingly broad, and its branches include now many extensions, such as the skew-elliptical families, and some forms of semi-parametric formulations, extending the relevance of the field much beyond the original theme of skewness. The final part of the paper illustrates connections with various areas of application, including selective sampling, models for compositional data, robust methods, some problems in econometrics, non-linear time series, especially in connection with financial data, and more. ...

Abstract: This paper presents a statistical study on a neuro-inspired spike-based implementation of the Vector-Integration-To-End-Point motor controller (SVITE) and compares its deterministic neuron-model stream of spikes with a proposed modification that converts the model, and thus the controller, in a Poisson like spike stream distribution. A set of hardware pseudo-random numbers generators, based on a Linear Feedback Shift Register (LFSR), have been introduced in the neuron-model so that they reach a closer biological neuron behavior. To validate the new neuron-model behavior a comparison between the Inter-Spikes-Interval empirical data and the Exponential and Gamma distributions has been carried out using the Kolmogorov-Smirnoff test. An in-hardware validation of the controller has been performed in a Spartan6 FPGA to drive directly with spikes DC motors from robotics to study the behavior and viability of the modified controller with random components ...

For testing the hypothesisHdthat the law ofX1is some nondegenerate normal distribution, there is a whole class of practicable affine invariant and universally consistent tests. These procedures are based on weighted integrals of the squared modulus of the difference between the empirical characteristic function of the scaled residualsYj=S-1/2(Xj-X) and its almost sure pointwise limit exp(-||t||2/2) underHd.

By working in the Fréchet space of continuous functions on d, we obtain a new representation of the limiting null distributions of the test statistics and show that the tests have asymptotic power against sequences of contiguous alternatives

Choosing Analyze:Distribution ( Y ) gives you access to a variety of distribution analyses. For nominal Y variables, you can generate bar charts, mosaic plots, and frequency counts tables. For interval variables, you can generate univariate statistics, such as moments, quantiles, confidence intervals for the mean, standard deviation, and variance, tests for location, frequency counts, robust measures of the scale, tests for normality, and trimmed and Winsorized means. You can use parametric estimation based on normal, lognormal, exponential, or Weibull distributions to estimate density and cumulative distribution functions and to generate quantile-quantile plots. You can also generate nonparametric density estimates based on normal, triangular, or quadratic kernels. You can use Kolmogorov statistics to generate confidence bands for the cumulative distribution and to test the hypothesis that the data are from a completely specified distribution with known parameters. You can also test the ...

is the standard deviation, and N is the number of data points. Note that in computing the skewness, the s is computed with N in the denominator rather than N - 1. The above formula for skewness is referred to as the Fisher-Pearson coefficient of skewness. Many software programs actually compute the adjusted Fisher-Pearson coefficient of skewness $G_{1} = \frac{\sqrt{N(N-1)}}{N-2} \frac{\sum_{i=1}^{N}(Y_{i} - \bar{Y})^{3}/N} {s^{3}}$ This is an adjustment for sample size. The adjustment approaches 1 as N gets large. For reference, the adjustment factor is 1.49 for N = 5, 1.19 for N = 10, 1.08 for N = 20, 1.05 for N = 30, and 1.02 for N = 100. The skewness for a normal distribution is zero, and any symmetric data should have a skewness near zero. Negative values for the skewness indicate data that are skewed left and positive values for the skewness indicate data that are skewed right. By skewed left, we mean that the left tail is long relative to the right tail. Similarly, skewed right means ...
In this work our aim is to estimate the distribution of the maximum between variables representing the natural logarithm of the PM10 emission in two stations of the town of Cagliari in Italy in 2004. It turns out that such order statistic has a skew normal distribution with skew parameter which can be expressed as a function of the correlation coefficient between the two initial variables. The skew-normal distribution belongs to a family of distributions which includes the normal one along with an extra parameter to regulate skewness. Azzalini (1985) was the first to introduce the skew-normal distribution and studied some of its properties. Loperfido (2002) showed that the distribution of the maximum between two standardized correlated normal variables, with correlation coefficient rho, is Skew-Normal with parameter lambda which depend of the correlation coefficient rho. In this specific case we show how is possible, using some theoretical results involving the correlation coefficient, to find ...
In this paper, we introduce a new approximation for the null distribution of the likelihood ratio test for the general case. We compare the the critical values obtained by the new approximation to the values which are obtained by the exact distribution for the cases k=1, 2 to test the accuracy of the new approximation. Also, we compare the results to another approximation method (which is known by Barnett and Lewis (1994)) for the cases k=3,4.. ...

Obesity remains a growing problem in many Western countries including Australia, where 63% of the adult population is overweight or obese.1 Among developed countries, the economic costs associated with overweight and obesity are significant.2 There is growing interest in understanding how the neighbourhood environment may influence the risk of overweight and obesity by encouraging increased energy consumption and discouraging energy expenditure. While it seems plausible that the rise in obesity can be partly attributed to the built environment, the abundant literature examining aspects of the built environment in relation to weight status has yielded equivocal results, with calls for better metrics to evaluate associations.3 Examination of destinations, an increasingly common focus of neighbourhood research, has yielded mixed results: inverse relationships between body mass index (BMI) and grocery or supermarket store availability have been observed in some research,4-6 while positive ...

AIM OF STUDY: To develop an early warning score (EWS) system based on the statistical properties of the vital signs in at-risk hospitalised patients. MATERIALS AND METHODS: A large dataset comprising 64,622 h of vital-sign data, acquired from 863 acutely ill in-hospital patients using bedside monitors, was used to investigate the statistical properties of the four main vital signs. Normalised histograms and cumulative distribution functions were plotted for each of the four variables. A centile-based alerting system was modelled using the aggregated database. RESULTS: The means and standard deviations of our populations vital signs are very similar to those published in previous studies. When compared with EWS systems based on a future outcome, the cut-off values in our system are most different for respiratory rate and systolic blood pressure. With four-hourly observations in a 12-h shift, about 1 in 8 at-risk patients would trigger our alerting system during the shift. CONCLUSIONS: A centile-based Finding interesting symmetrical topological structures in high-dimensional systems is an important problem in statistical machine learning. Limited amount of available high-dimensional data and its sensitivity to noise pose computational challenges to find symmetry. Our paper presents a new method to find local symmetries in a low-dimensional 2-D grid structure which is embedded in high-dimensional structure. To compute the symmetry in a grid structure, we introduce three legal grid moves (i) Commutation (ii) Cyclic Permutation (iii) Stabilization on sets of local grid squares, grid blocks. The three grid moves are legal transformations as they preserve the statistical distribution of hamming distances in each grid block. We propose and coin the term of grid symmetry of data on the 2-D data grid as the invariance of statistical distributions of hamming distance are preserved after a sequence of grid moves. We have computed and analyzed the grid symmetry of data on multivariate Gaussian ... In this fully revised and expanded edition of Smooth Tests of Goodness of Fit, the latest powerful techniques for assessing statistical and probabilistic models using this proven class of procedures are presented in a practical and easily accessible manner. Emphasis is placed on modern developments such as data-driven tests, diagnostic properties, and model selection techniques. Applicable to most statistical distributions, the methodology described in this book is optimal for deriving tests of fit for new distributions and complex probabilistic models, and is a standard against which new procedures should be compared. New features of the second edition include: Expansion of the methodology to cover virtually any statistical distribution, including exponential families. Discussion and application of data-driven smooth tests. Techniques for the selection of the best model for the data, with a guide to acceptable alternatives.

While primary tumors are often treated effectively, they can spawn secondary cancers called metastases which dramatically decrease chances of survival. In order to develop successful therapies, it is thus crucial to estimate the time until metastases appearance and improve our ability to detect primary tumors before metastases are generated. The estimation of the time to cancer recurrence depends on the dynamics of tumor growth and metastases seeding. For early detection, promising results have recently been obtained with liquid biopsies, id est the analysis of specific biomarker levels in blood samples. This thesis investigates these problems by studying mathematical models of cancer evolution and liquid biopsies based on the theory of branching processes. Firstly, we consider first passage times to a given size in branching birth-death processes. We derive their probability distribution and first moments conditioned on non-extinction, ... A value, x, from a normal distribution specified by a mean of m and a standard deviation of s can be converted to a corresponding value, z, in a standard normal distribution with the transformation z=(x-m)/s. And, of course, in reverse, any value from a standard normal graph, say z, can be converted to a corresponding value on a normal distribution with a mean of m and a standard deviation of s by the formula x=m+z*s. Remember that the standard normal distribution has a mean of 0 and a standard deviation of 1, i.e., m=0, s=1.. The ability to carry out this transformation is very important since we can do all our analysis with the standard normal distribution and then apply the results to every other normal distribution, including the one of interest. For example, to draw a normal curve with a mean of 10 and a standard deviation of 2 (m=10, s=2), draw the standard normal distribution and just re-label the axis. The first figure below is the standard normal curve and the next figure is the curve ... Subrandom numbers have an advantage over pure random numbers in that they cover the domain of interest quickly and evenly. They have an advantage over purely deterministic methods in that deterministic methods only give high accuracy when the number of datapoints is pre-set whereas in using subrandom sequences the accuracy typically improves continually as more datapoints are added, with full reuse of the existing points. On the other hand, subrandom sets can have a significant lower discrepancy for a given number of points than purely random sequences. Two useful applications are in finding the characteristic function of a probability density function, and in finding the derivative function of a deterministic function with a small amount of noise. Subrandom numbers allow higher-order moments to be calculated to high accuracy very quickly. Applications that dont involve sorting would be in finding the mean, standard deviation, skewness and kurtosis of a statistical distribution, and in finding ... TY - JOUR.

Given two independent non-degenerate positive random variables X and Y, Letac and Wesolowski (Ann. Probab. 28 (2000) 1371) proved that U=(X+Y)-1 and V=X-1-(X+Y)-1 are independent if and only if X and Y are generalized inverse Gaussian (GIG) and gamma distributed, respectively. Note that X=(U+V)-1 and Y=U-1-(U+V)-1. This interesting transformation between (X,Y) and (U,V) preserves a bivariate probability measure which is a product of GIG and gamma distributions. In this work, characterizations of the GIG and gamma distributions through the constancy of regressions of Vr on U are considered. Its values lie between -2 and +2.. If$S_k$is greater than zero, the distribution or curve is said to be positive skewed. If$S_k$is less than zero the distribution or curve is said to be negative skewed. If$S_k\$ is zero the distribution or curve is said to be symmetrical.. The skewness of the distribution of a real valued random variable can easily be seen by drawing histogram or frequency curve.. The skewness may be very extreme and in such a case these are called J-shaped distributions.. ...
The frequency of occurence of a given amplitude (or value) from a finite number of realizations of a random variable can be displayed by dividing the range of possible values of the random variables into a number of slots (or windows). Since all possible values are covered, each realization fits into only one window. For every realization a count is entered into the appropriate window. When all the realizations have been considered, the number of counts in each window is divided by the total number of realizations. The result is called the histogram (or frequency of occurence diagram). From the definitioin it follows immediately that the sum of the values of all the windows is exactly one. The shape of a histogram depends on the statistical distribution of the random variable, but it also depends on the total number of realizations, N, and the size of the slots ...

Kurtosis tells you virtually nothing about the shape of the peak - its only unambiguous interpretation is in terms of tail extremity; i.e., either existing outliers (for the sample kurtosis) or propensity to produce outliers (for the kurtosis of a probability distribution). See Kurtosis as Peakedness, 1905 - 2014. R.I.P., Peter H. WESTFALL ...
Within the EFSA Article 36 project European Tool Usual Intake (ETUI) a workshop was organised in May 2010 where the different available models to calculate usual intake were presented and discussed. This report integrates the workshop background document, the presentations given by experts, and the discussions during the workshop. The purpose of the workshop was to evaluate existing statistical methods for estimating usual intake with respect to a number of criteria, so that the performance of each method on each criterion will be well understood after the workshop. The outcome of the workshop allows choices to be made for a European Tool Usual Intake, to be implemented in the remainder of the project. A starting document was provided to the participants of the workshop with up-to-date information on methods, data and criteria, as a basis for discussion. It was apparent from the workshop that there is not one optimal model for all cases, rather a toolbox approach is suitable. The choice of the ...
The Jarque-Bera demo experiment can be used to generate the null distribution of the Jarque-Bera statistic for any number of variables (N). The Jarque-Bera statistic has asymptotically the Chi-square distribution with two degrees of freedom, i.e., StatsChiCDF(x,2). For small value of N the actual distribution is sufficiently different from the asymptotic values.. The calculation consists of a Monte-Carlo simulation which computes the Jarque-Bera statistic for many realizations of N random samples from a normal distribution. The wave containing the statistic is histogramed (using the /P flag it is also normalized as a PDF) and then integrated to get the corresponding CDF. To obtain the critical value you can solve for the point at which the CDF equals 1-alpha, where alpha is the desired significance.. To run the simulation execute the following command.. ...
The sum of a discrete probability distribution should always be 1, correct? For the distribution shown at 6:00, sum_x Q(x) = 1+epsilon which doesnt equal 1.. Somebody please answer if we are missing something?. ...
The course gives an overview over important models and techniques for regression analysis outside standard linear regression. In particular, the students will learn how to extend the linear model for response variables with binary/binomial, Poisson and gamma distributions. Furthermore, the students will learn about regression methods for dependent response variables.. ...

My answers in bold The only reason you dont believe is because you dont want to be obedient. I dont give a rats ass - thats why I dont believe. Evolution is just a theory! First of all whoever says things like this dont understand evolution. Its not a linear process but a branching process.…
Modified Value-at-Risk (mVaR) and Modified Expected Shortfall (mES) are risk estimators that can be calculated without modelling the distribution of asset returns. These modifided estimators use skewness and kurtosis corrections to normal distribution parametric VaR and ES formulas to reduce bias in risk measurement for ...
