(eng): The contribution deals with statistical tests of model fit. We recall the notion of martingale residuals defined for lifetime models based on failure intensities. Analysis of these residual processes has already been studied by many authors. Nevertheless, Bayes approach to this problem is just developing. We shall present a Bayes procedure of estimation in Cox's and AFT models semi-parametric models. Our main concern is Bayes construction of residual processes and goodness-of-fit tests based on them. The method will be illustrated on an example with randomly generated data.
