This paper discusses a model for regression analysis with a time series of counts. Correlation is assumed to arise from an unobservable process added to the linear predictor in a log linear model. An ...

Deletion diagnostics are proposed for generalised estimating equations. The diagnostics consider leverage and residuals to measure the influence of a subset of observations on the estimated regression ...
