st: Poisson regression - Test of goodness of fit

[Alexandra Boing <alexandraboing@yahoo.com.br>]

I have doubts about the use of poisgof - Test of goodness of fit (command Stata 8= poisgof Stata 9= estat gof) in a Poisson regression in which I have to run with svy. The poisgof and estat gof not accepted. Is acceptable only when run a Poisson regression without the svy.
How should I proceed as it is necessary to use in my case the svy? What is problem run Test of goodness of fit (poisgof OR estat gof) with Poisson regression without svy. This is a problem?
Another question I have a model output and doubt in the interpretation of the output: pseudo R2=0.0562, LRchi2(6)=71,46, goodnessfit=789.0331, chi2(1665)=1.0000
This is good? Is appropriate? What is best option of analyse?


Poisson regression                           Number of obs   =       1672
                                             LR chi2(6)      =      71.46
                                             Prob > chi2     =     0.0000
Log likelihood = -599.51655                  Pseudo R2       =     0.0562



Goodness-of-fit chi2  =  789.0331
         Prob > chi2(1665)     =    1.0000
