Bayesian Bootstrap Clones for Censored Markov Chains
Authors:Wen‐Liang Hung
Abstract:In this article, we consider r observations equation image from a non‐homogeneous censored Markov chain, with transition probability matrix P. For the product estimator equation image of P proposed by Aalen and Johansen (1978) and Phelan (1988), we investigate the behavior of Bayesian bootstrap clones to approximate the sampling distribution of equation image , and then construct approximate confidence interval. It is shown that the approximation based on the random‐weighted distribution is first‐order consistent. The performance of the Bayesian bootstrap clones (BBC) is also discussed by small sample simulation. Finally, we illustrate the BBC procedure in the application to the WHO malaria survey data (cf. Singer and Cohen 1970).
Keywords:Bayesian bootstrap clones  Censored Markov chain  Product estimator  Transition probability matrix
