Hi,
I am using the following command to fit my data:
nbreg outcome i.exposure [pweight=weight], irr
I have used the prcounts command and twoway to plot my observed vs. predicted poisson vs. predicted negative binomial – I am confident my data fits a negative binomial distribution. However, when I use the command stated above I do not recieve a likelihood ratio test for alpha=0 in the output as I see in example outputs in the documentation for this command. I would like to see this, is there a way to obtain this output or any ideas as to why I am not receiving this output?
Thanks
Robyn
