We also discuss fitting the GF with an alternative parameterization using standard statistical software and refine a description of the hazard functions for death after a diagnosis of clinical AIDS in four different eras of HIV therapy. Examples of such distributions are the Cook's D I statistics and the Hotelling's T test when the covariance is misspecified. Annu Rev Public Health. Survival analysis based on the GG distribution is practical since regression models are available in commonly used statistical packages. NLM 2016 May 12;70:i08. In a recent tutorial my colleagues and I advocated the generalized gamma (GG) distribution as a platform for parametric survival analysis. How Uncertain is the Survival Extrapolation?

It is well known that the GG is contained in an even larger family, the generalized F (GF) distribution, which also includes the log logistic. Their connection with the Gauss hypergeometric function and Lauricella functions leads to further generalizations … Page views:: 6776. Epub 2008 Nov 12.
