I just posted a response which shows how to compute dfbetas for -stcox-
(http://www.hsph.harvard.edu/cgi-bin/lwgate/STATALIST/archives/statalist.1203/date/article-664.html)
and it should also work for -xtnbreg-

I have identified some outliers in my dataset but now I want to know whether they are influential points as well.
There are plenty of ways to do this using regress but I am using xtnbreg and so far I did not come across any test like the Cook's test that applies to xtnbreg. Can someone suggest how should I proceed?
