• Estimators
  • He was a distinguished mathematical statistician whose wide-ranging research included the analysis of martingale inequalities, Markov processes, de Finetti's theorem, consistency of Bayes estimators, sampling, the bootstrap, and procedures for testing and evaluating models. (wikipedia.org)
  • Covariates
  • The log of the survival time is modeled as a linear effect of covariates and a random disturbance term, the distribution of which includes the Weibull, log-normal, and log-logistic distributions. (sas.com)
  • mortality
  • When someone is interested in how survival is affected by the disease, there is also the net survival rate, which filters out the effect of mortality from other causes than the disease. (wikipedia.org)
  • Differences
  • Differences in mean survival times were identified in children not more than 4 months of age with respect to the following diagnoses: impaired gas exchange, ineffective breathing pattern, activity intolerance, delayed growth and development, and decreased cardiac output. (redorbit.com)
  • Methods
  • Each included study may be assigned an objective assessment of methodological quality preferably by using methods conforming to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement (the current guideline) or the high quality standards of Cochrane. (wikipedia.org)
  • rates
  • a class of statistical procedures for estimating survival rates and making inferences about effects of treatment, prognostic factors, and other concerns. (drugs.com)
  • To analyze the relationship between nursing diagnoses and survival rates in children with congenital heart disease. (redorbit.com)
  • In survival analysis, the hazard ratio (HR) is the ratio of the hazard rates corresponding to the conditions described by two levels of an explanatory variable. (wikipedia.org)
  • Survival rates are important for prognosis, but because the rate is based on the population as a whole, an individual prognosis may be different depending on newer treatments since the last statistical analysis as well as the overall general health of the patient. (wikipedia.org)
  • citation needed] There are various types of survival rates (discussed below). (wikipedia.org)
  • Death
  • In the case of biological survival, death is unambiguous, but for mechanical reliability, failure may not be well-defined, for there may well be mechanical systems in which failure is partial, a matter of degree, or not otherwise localized in time. (wikipedia.org)
  • in this context, death or failure is considered an "event" in the survival analysis literature - traditionally only a single event occurs for each subject, after which the organism or mechanism is dead or broken. (wikipedia.org)
  • disease
  • The purpose of this study was to analyze the survival of children with congenital heart disease in relation to nursing diagnoses. (redorbit.com)
  • cause specific survival has the advantage that it does not depend on the ability to find a similar population of people without the disease. (wikipedia.org)
  • These include the disease-free survival (DFS) (the period after curative treatment [disease eliminated] when no disease can be detected), the progression-free survival (PFS) (the period after treatment when disease [which could not be eliminated] remains stable, that is, does not progress), and the metastasis-free survival (MFS) or distant metastasis-free survival (DMFS) (the period until metastasis is detected).

  • mean
  • Note that in statements of the assumptions underlying regression analyses such as ordinary least squares, the phrase "no multicollinearity" is sometimes used to mean the absence of perfect multicollinearity, which is an exact (non-stochastic) linear relation among the regressors. (wikipedia.org)
  • literature
  • I believe one of the best things in my career development is that I first encountered the scientific process - critically - the analysis of literature, art and culture (i.e. anthropology). (andrewgelman.com)
  • Long term survival is currently even more promising, although this impression is not reflected in the recent literature. (wikipedia.org)
