If you could compute a table with 220,000 rows what you do with it? This does seem like a case in which a reduced dataset will be the most convenient solution. By the way, although -collapse- has already been mentioned for this, in some ways -contract- is more direct. Alternatively, consider bysort FSHNETCP3 luse_csp : gen sumcount = sum(count) by FSHNETCP3 luse_csp : replace sumcount = sumcount[_N] by FSHNETCP3 luse_csp : gen tag = _n == 1 list FSHNETCP3 luse_csp sumcount if tag Alternatively, consider -groups- from SSC. Nick n.j.cox@durham.ac.uk Martin I would like to calculate the values which I have in my table in this form: FSHNETCSP3 luse_csp count 0 10 500 0 1010 124 1 10 500 2 1010 240 2 10 120 3 1010 130 3 10 120 4 10 101 ...... To receive the following result: | luse_csp FSHNETCSP3 | 0 1 2 3 4 5 10 1000 | Total -----------+---------------------------------------------------------------- ------------------------+---------- 0 | 0 9 0 0 5 0 327 3 | 344 1 | 0 0 0 0 0 0 315 0 | 315 2 | 0 5 0 0 0 0 321 5 | 331 3 | 0 0 0 0 0 0 439 1 | 440 4 | 0 0 0 0 0 0 412 8 | 420 5 | 1 2 3 0 0 0 440 0 | 446 6 | 0 0 0 0 0 0 413 7 | 420 ........ I used the following command: . tabulate FSHNETCSP3 luse_csp [fweight = count] in 1/1000 However, because I have 220.000 different FSHNETCSP3 values I get the error "too many values". I tried the "bigtab" command from the list, but there I can`t add a weight. I don`t want to use collapse because I need the exact values for further calculations. * * 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/
