Dear Statalisters I have a dataset like the following, where the SIC values are in an ascending order SIC EXP 2011 667.8039 2013 130.8002 . . . . 2095 38.90306 2098 0.617763 2111 249.92 2121 3.738577 2131 35.32281 . . . 2298 5.709858 2299 39.7519 . . etc What I want to find is the sum of EXP values that have a SIC value begining with 20, i.e. 667.8039+130.8002+..+38.90306+0.617763 In others words I have some 4digit SIC data and I want to aggregate them into 2digit SIC. Any hint is really appreciated * * For searches and help try: * http://www.stata.com/support/faqs/res/findit.html * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
