Hello All: I have a big panel dataset (150,000 observations) and I want to use DEA methodology to calculate efficiency of lets say production (with production as output and four other input variables). However, my problem is that I want to do that for every 2-digit industry code. I am wondering if there is an efficient way to do so. Following is the command I would use if I need to do it for 5 firms in an year. dea input = output, sav(eff_results) use eff_results, clear tobit theta independent_variables, ul(1) Can someone please help me expand the above set of commands and use it in the setting that I describe above. Thanks, Sarfraz * * 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/
