<> "-statsby- is what has been called a reduction command. It replaces the present dataset" -statsby- can be made to save its results with the -saving()- option, though, instead of forcing out the original data: *** sysuse auto, clear statsby _b, by(rep78) saving(myfile, replace) : reg pr we le *** HTH Martin -----Original Message----- From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Nick Cox Sent: Dienstag, 1.

It replaces the present dataset with a reduced set of results, one observation for each group. Nick n.j.cox@durham.ac.uk Martin Weiss Also note -statsby-, -postfile-`s smaller brother. Sometimes it is sufficient to get where you want. It is much simpler to use, but you lose the versatility of -postfile-. Re -statsby-, see NJC`s recent column at http://www.stata-journal.com/article.html?article=gr0045. Martin Weiss This cries out for the use of -postfile-, as in Michael`s http://www.michaelnormanmitchell.com/stow/posting-results-regression.html and two following posts, or check the archive, as in http://www.stata.com/statalist/archive/2009-10/msg01043.html. George Chioran I want to store the results that I obtain from several while loops. First I have the time variable “t”: 1, 2, 3, … and are in total 16. Then I have the accounts “a”: 210, 245, 256, … and are in total 700. In time period 1 I get a different result for all 700 account. In time period 2 the same happens and so on. I would like to somehow save the results that I get from each account under each period. My code goes like this: local t = 1 local a = 1 While `t’ <= 16 { While `a’ <= 700 { ….. In this loop I get the results for a = 1 which is r1, for a = 2 which is r2 and so on. Could I somehow save the results r1, r2,… in a new stata sheet? local a = `a’+1 } local t = `t’ +1 } I would like the results to be placed in a table like this: ta result 1 210 r1 1 245 r2 1 256 r3 … … … 2 210 r1 2 245 r2 2 256 r3 … … … So when the loop with variable t is at 1, the table should put in the first column only 1, in the second column the current account and in the third column the result of the current account. * * 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/ * * 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/
