Chapter 7 Survival ModelsOur final chapter concerns Models for the analysis of data which have threemain characteristics: (1) the dependent variable or response is the waitingtimeuntil the occurrence of a well-defined event, (2) observations arecen-sored, in the sense that for some units the event of interest has not occurredat the time the data are analyzed, and (3) there are predictors orexplanatoryvariables whose effect on the waiting time we wish to assess or control. Westart with some basic The Hazard and Survival FunctionsLetTbe a non-negative random variable representing the waiting time untilthe occurrence of an event. For simplicity we will adopt the terminologyof Survival analysis, referring to the event of interest as death and to thewaiting time as Survival time, but the techniques to be studied have muchwider applicability.

The Gompertz distribution is characterized by the fact that the log of the hazard is linear in t, so (t) = expf + tg and is thus closely related to the Weibull distribution where the log of the hazard is linear in logt. In fact, the Gompertz is a log-Weibull distribution. This distribution provides a remarkably close t to adult mortality in

Generalized Linear Model Theory - Princeton University

B.2 Maximum Likelihood Estimation An important practical feature of generalized linear models is that they can all be fit to data using the same algorithm, a form of iteratively re-weighted least squares. In this section we describe the algorithm. Given a trial estimate of the parameters βˆ, we calculate the estimated linear predictor ˆη i ...
