Check your memory settings first: memory set memory 640m This should suffice for variables stored as doubles (8 bytes x 3M observations x 20 variables = 480Mb, plus some 33% overhead). If you indeed have "War and Peace" coded as string variables, with one observation per paragraph, then things will certainly get more complicated, as other people have indicated, but that's hardly a good way to treat this masterpiece. -- Stas Kolenikov, also found at http://stas.kolenikov.name Small print: I use this email account for mailing lists only. * * 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/
