Hi,

To reproduce some part of Table 3.4 in Cameron and Trivedi (1998) book "Regression analysis of count data", I found this help file from Stata Corp FAQs (http://www.stata.com/support/faqs/stat/nbreg1.html).

I ran nbreg, dispersion(constant) , but the resulted standard errors for beta are very different from what's reported in the MLE column and similar to the GLM column. Could someone tell me why?

Thanks,

Zhehui
