Hello. I need help about dropping observation. I have several variables and nearly 1350 obvervations. Some observations have negative (-) values, e.g. -1, -3, for some observation. How can I drop ALL observation who have any negative values for any variables? I tried "drop if", "keep if", for example, drop if siyasigorus < 0, but it did not work or i could not do properly. * * 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/
