%description
This work is an extension of the state space model for Poisson count data,
Poisson-Gamma model, towards a semiparametric specification. Just like the
generalized additive models (GAM), cubic splines are used for covariate
smoothing. The semiparametric models are fitted by an iterative process
that combines maximization of likelihood and backfitting algorithm.
