title: David Byar's approach to the analysis of survival data with covariates.
abstract: The analysis of censored survival data with covariates was central to most of David Byar's research in cancer epidemiology and clinical trials. His general approach is outlined briefly, with particular reference to the construction of risk groups. Other topics include the choice between fully and semiparametric models, and the interpretation of interactions.
