The study investigated the estimation of the cumulative hazard function for mixed right-censored and current status data. Tian-yo Wang (2015) used Bayesian approach to estimate their distribution function. The study used Bayesian statistics and Markov chain Monte Carlo method to calculate the similar data, which is different in estimated cumulative hazard function. We chose to directly estimate cumulative hazard function because it was a special case of Cartesian model. Considering the covariate, we will use the method to estimate the data. Its simulation results consistent with theoretical.
