I may be taking this completely out of context, but if this is the case, there is an argument that logistic regression is inappropriate, and cloglog regression (which has a hazard rate interpretation) would be better.

This causes problems in the xtlogit too, where the cases are not dropped. > 5 | -55.3464 4613.941 -0.01 0.990 -9098.504 8987.812 Regards, Brendan -- Brendan Halpin, Department of Sociology, University of Limerick, Ireland Tel: w +353-61-213147 f +353-61-202569 h +353-61-338562; Room F1-009 x 3147 mailto:brendan.halpin@ul.ie ULSociology on Facebook: http://on.fb.me/fjIK9t http://teaching.sociology.ul.ie/bhalpin/wordpress twitter:@ULSociology * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
