Count Longitudinal Data
Description
Performs Poisson regression analysis for longitudinal count data, allowing for serial dependence among observations from a given individual and two random effects. Estimation is via maximization of the exact likelihood of a suitably defined model. Missing values and unbalanced data are allowed.
Details
This package contains functions to perform the fit of parametric models via likelihood method for count longitudinal data using "S4" classes and methods as implemented in the methods package.
