The main concept of this thesis is the research of analysis of survival data of cured subgroups’current status. We apply Bayesian method and M.C.M.C. algorithm to conduct data analysis and estimation, respectively. In this thesis, we provide two algorithms; one is increasing algorithm, and the other is concave-downward-increasing algorithm, to compare the results. It is faster and of higher accuracy to conduct the estimation with the later if the real function is increasing and concave downwards. Besides, it performs great when manipulating calculation.
