Webb8 sep. 2024 · For this type of data, the aims of a time-to-event analysis are usually (a) to descriptively summarize information on event times and observed events, (b) to build a statistical model incorporating the covariate information, and (c) to conduct hypothesis tests on the effects of the covariates on event occurrence. WebbThe majority of existing rate regression methods assume multiplicative covariate effects. We propose a semiparametric model for the marginal recurrent event rate, wherein the covariates are assumed to add to the unspecified baseline rate. Covariate effects are summarized by rate differences, meaning that the absolute effect on the rate function ...
