Semiparametric Bayesian estimation of mixed count regression models

Author

  • Zheng, Xiaoyong

Abstract

This paper develops semiparametric Bayesian estimation approach for Poisson regression models with unobserved heterogeneity of unknown density. This approach is computationally efficient and allows automatic adaptation of the approximating density to data during estimation. Simulations show the estimator performs well.
