Dear all, I'm trying to run DEA with a panel of 150 hospitals. As an illustration, to get an idea of how it works, I tried the example provided by Scott Merryman in this forum: sysuse auto,clear keep in 1/5 rename make dmu dea length weight = mpg, saving(deaout) use deaout,clear tobit theta price, ul(1) But immediately after the command: dea length weight = mpg, saving(deaout) : I receive: too few variables specified Any idea what might be the reason? I have installed all the files under findit dea Thanks in advance, Anat Tchetchik, PhD Department of Business Administration Guilford Glazer Faculty of Business and Management Ben-Gurion University of the Negev P.O.Box: 653 Beer-Sheva, Israel, 84105 E-mail: anat@som.bgu.ac.il Phone 972-(0)8-6479735 Fax: 972-(0)8-6472920 * * 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/
