Line for the server... We had a presentation at the San Francisco UGM this year that advocated an increase in the number of warnings in Stata http://www.stata.com/meeting/fnasug08/epstein_stata_november_2008.ppt but support for the idea during the discussion was certainly weak... Warnings like the -xtmixed- output stating that the lrtest is conservative, with a link to a help file containing a more comprehensive explanation, seem appropriate to me. Personally, I like Stata`s conservative approach to warnings. Also note that Stata prevents you from doing unreasonable things entirely in some cases. http://www.stata.com/statalist/archive/2008-11/msg00984.html is a good recent example. If you interpret Stata`s refusal to do something as a severe warning, then the number of warnings suddenly increases dramatically...

I would take note of more warnings if and when they existed and I am happy to believe that they would be widely welcomed. But the trade-off between yet more work that somebody (i.e. the Stata developers) has to do in adding warnings, work that would displace developing other stuff that we want the company to do _soon_, no right _now_, is very delicate. I like the Stata philosophy that users take responsibility for finding out and that we don't want or need little nagging warnings all the time. Nick n.j.cox@durham.ac.uk David Kantor Here's a suggestion to StataCorp and to anyone who writes programs and then changes the names of programs or options or syntax. (I've done this on at least one occasion.) Allow the old names or syntax to continue working, but issue a warning message alerting users to the change, whenever they are used. For those who would object to the possible intrusion of these messages, perhaps there could be an environmental variable to switch this on and off. * * 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/ * * 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/
