This package allows for semiparametric regression analysis of panel count data under the non-homogeneous Poisson process models with and without frailty. The Gamma frailty model allows to account for the within-subject correlation. Monotone splines of Ramsay (1988) are used to estimate the unknown baseline mean function. Fitting the models to panel count data via EM algorithm.
