Hi all--I'm trying to create at table of summary stats of a two group sample that includes group means and standard deviations and the p-value of a ttest of difference in means. I'm using -esttab- and can get the means and p-values from -espost ttest-. I'm running into a problem getting the standard deviations though. I have been trying to use -estpost summarize- and then -estadd- to add the standard deviations to the estimates I've stored from -estpost ttest-. When I look at the stored estimates after -estpost summarize- it shows e(sd) as a 1x7 matrix, but when I use -estadd- to add that matrix to the stored estimates from -estpost ttest-, e(sd) is added as a 1x1 matrix that is simply the standard deviation of the last variable in my varlist for -estpost summarize-. Below is my code. eststo est1: estpost ttest $variables, by(treedummy) bysort treedummy: eststo: estpost summarize $variables //after this command if I use -ereturn list-, e(sd) is 1x7 estadd matrix sd1=e(sd): est1 sd1 is added to the stored estimates "est1", but only as a 1x1 matrix. I appreciate any thoughts. Mike * * 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/
