Before you jump to any conclusions about the machine not working make sure that the cord's plugged in. Did you forget a weighting term or did listwise deletion dump most of your cases? Standard errors of these cutoffs should be proportional to 1/sqrt(n) and these are huge. Usually what happens with a crappy model is that the terms end up not separated, but that's not what you have here. * * 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/
