Abstract

A Bivariate survival model is constructed.This model is based on a frailty model that acts multiplicatively on the hazard function. We consider a uniform frailty.We introduce external covariates by an accelerated life model. That model called mixed by us is considered to study some measures of association for example the Kendall coefficient. We state the problem of the estimation with Weibull marginals.
