Abstract(in English) | Cox's proportional hazards model (PHM) has been widely applied in the analysis of lifetime data. It involves covariates influencing the times to the failure of a system. In this article, the covariates are assumed to be discrete random variables, and a mixed proportional hazards model is derived. We consider three types of data; one type of experimental data and two types of field data. We investigate estimation in the mixed PHM with these three types of data. We develop maximum likelihood techniques for joint estimation of distribution parameters, mixing proportions, and a regression parameter using the Expectation-Maximization(EM) algorithm. |
