Applications of Non-Homogeneous Markov Chains to Medical Studies
Recently, AALEN (1978) has shown how the modern theory of stochastic processes may be a useful tool in developing nonparametric estimation and testing procedures of interest in medicine and related fields. The purpose of the present paper is to give a nontechnical review of his results and some extensions of these, and to discuss problems connected with a nonparametric analysis of retrospective data.
