estat gof performs a goodness-of-fit test of the model.The default is the deviance statistic;specifying option pearson will give the Pearson statistic.If the test is significant,the Poisson regression model is inappropriate.Then you could try a negative binomial model;see[R]nbreg.1 ...
In the Poisson regression model, the incidence rate for the jth observation is assumed to be given by r = ej β0+β1x1,j +···+βkxk,j If Ej is the exposure, the expected number of events, Cj, will be Cj = E ej β0+β1x1,j +···+βkxk,j = e ln(Ej )+β0+β1...
In each case, the exponentiated regression coefficient exp{β 1ijk} yields an incidence rate ratio (IRR), which represents a multiplicative effect of the kth predictor on the mean. A one log-unit increase in x k multiplies the mean by a factor exp{β 1k}. Table 1 shows the results of...

In this article, we will describe how to analyze the data used in our previous article1 regarding implant failures with Poisson regression. We are interested in examining whether the rate of implant failure is different between smokers and nonsmokers. In other words, we are interested in the r...

The mixed-effects Poisson regression model can also be used in meta- analyses of incidence or any other type of counts or rates. We have also shown that the model could be extended to handle situations of meta-analysis of mutually exclusive data (competing risks). The application of the ...
