Proportional hazards models, general situation can be described by a model with a parameter of high, possibly unbounded, dimension. We refer to this as the general or non-proportional hazards model since dependence is expressed via a parameter, . that is not constrained or restricted. Proportional hazards models have the same

Proportional hazards models in epidemiology,isk, where the time factor is now age, and we see how our survival models can be used to control for the effects of age. Series of . tables, familiar to epidemiologists, can be structured within the regression model setting. The well-known Mantel-Haenszel test arises as a model-based score test. Log

Hypothesis tests based on regression effect process,vide us with an extensive array of tools for the hypothesis testing problem. Importantly, all of these tests can be readily derived from within the proportional and non-proportional hazards framework. Given our focus on the regression effect process, it is equally important to note that these tests

Introduction, a brief section headed “Chapter summary”. Section . is the first such summary. Following these summaries comes a section headed “Context and motivation”, the purpose of which is to motivate our interest as well as to recall any key notions we may need as an aid in pursuing the topic of the chapter.

Proportional hazards models,l backgrounds that lay behind Cox’s proposal is also recalled in order to for the new reader to quickly appreciate that, brilliant though Professor Cox’s insights were, they leant on more than just his imagination. They did not emerge from a vacuum. Some discussion on how the model should be used in

Model-based estimating equations,er independent censoring and non-constant . One example we show, under heavy censoring, indicates the commonly used partial likelihood estimate to converge to a value greater than 4 times its true value. Linear estimating equations provide a way to investigate statistical behavior of estimates for s
