Thank you getting back, I will try Laplace.

Sounds like you're trying to fit a very complex model, which will take a long time due to the fact that adaptive quadrature is being used by -xtmelogit-. You may want to switch to the Laplace approximation to see if that speeds things up and then use adaptive quadrature only on the final model. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
