st: exact poisson regression

[Tracy Clegg <tracy.clegg@ucd.ie>]

Could anyone tell me whether there is a way to assess the goodness of fit
for an exact poisson regression model?

 

In addition does anyone know of a way to compare non-nested exact poisson
regression models?  I have been using STATA to carry out the analysis.

 

Any help would be much appreciated.
