• estimation
• Using the general theory of estimation and the results of Patil (1965) and Patel (1978) we give the tables of MVUE's for functions of parameter θ of trinomial, multinomial, negative-multinomial and left-truncated modified power series distributions. (eudml.org)
• The chi-squared distribution is used in the common chi-squared tests for goodness of fit of an observed distribution to a theoretical one, the independence of two criteria of classification of qualitative data, and in confidence interval estimation for a population standard deviation of a normal distribution from a sample standard deviation. (wikipedia.org)
• In statistics, minimum chi-square estimation is a method of estimation of unobserved quantities based on observed data. (wikipedia.org)
• value
• If our value of chi square from the formula is greater than the critical value of chi square, we reject H o and conclude that the obtained frequencies differ from the expected frequencies more than would be predicted by chance. (symynet.com)
• Define a new random variable Q. To generate a random sample from Q, take a sample from Z and square the value. (wikipedia.org)
• Numerical computation shows that the value of λ that minimizes the chi-square statistic is about 3.5242. (wikipedia.org)
• For that value of λ, the chi-square statistic is about 3.062764. (wikipedia.org)
• general
• There is no significant difference in the gender distribution between theater goers and the general college. (coursehero.com)
• The most general form of generalized chi-squared distribution is obtained by extending the above consideration in two ways: firstly, to allow z to have a non-zero mean and, secondly, to include an additional linear combination of z in the definition of X. Note that, in the above formulation, A and B need not be positive definite. (wikipedia.org)
