Titel:
Generalized estimating equations for longitudinal generalized Poisson count data with regression effects on the mean and dispersion level. 
Abstract:
Generalized estimating equations (GEE) fit parameters based on sums of weighted residuals, which may be applied for example to the Poisson distribution. We discuss Generalized Poisson (GP) response data. This distribution has a more flexible variance function than the Poisson distribution and has an additional dispersion parameter. To fit this parameter, second level estimating equations based on covariance residuals are neces- sary. This requires knowledge of variances of empirical co...    »
