Bayesian Nonparametric Inference for Panel Count Data

Dr. Ye Liang, Department of Statistics

In this paper, the panel count data analysis for recurrent events is considered. Such analysis is useful for studying tumor or infection recurrences in both clinical trial and observational studies. A bivariate log-Gaussian Cox process model is proposed to jointly model the observation process and the recurrent event process. Bayesian nonparametric inference is proposed for simultaneously estimating regression parameters, bivariate frailty effects and baseline intensity functions. Inference is done through Markov chain Monte Carlo, with using the Riemann manifold Hamiltonian Monte Carlo for the high dimensional sampling. Predictive inference is also discussed under the Bayesian setting. The proposed method is shown to be efficient via simulation studies. Two data examples from clinical trials are analyzed to illustrate the proposed approach.
