I'm not sure why the formatting was altered on my last posting. Hopefully this will be correct. tempname out postfile `out' <output variable names here> using outfile, replace foreach var of varlist <variables to be analyzed> { qui ttest `var', by(case) post `out' ("`var'") (r(mu_2)) (r(sd_2)) (r(N_2)) (r(mu_1)) (r(sd_1)) (r(N_1)) } postclose `out' use outfile, clear qui { for var case sd1 control sd2: format X %6.2f format p %4.3f } list, clean noobs ______________________________ Paul F.

I use it to output a table comprising results from several t-tests. (Use -return list- to identify the which factors are available for use after your regression.) tempname out postfile `out' <output variable names here> using outfile, replace foreach var of varlist <variables to be analyzed { qui ttest `var', by(case) post `out' ("`var'") (r(mu_2)) (r(sd_2)) (r(N_2)) (r(mu_1)) (r(sd_1)) /* */ (r(N_1)) (r(p)) } postclose `out' use outfile, clear qui { for var case sd1 control sd2: format X %6.2f format p %4.3f } list, clean noobs *At this point, I just copy the output to a Word document.

Sent: Tuesday, November 23, 2004 4:12 PM To: [email protected] Subject: st: Extracting B coefs and p's from "foreach" regression Hi All, As part of preliminary descriptive analysis I need to examine pairwise correlations between the effect size and a large number of possible covariates. The tricky part is that I have discovered I need to examine pairwise correlations which take into account a random effects component. I can do this by specifying bivariate random effect regressions using a metaregW macro in a foreach command as below: ***** foreach var of varlist VarGrp1_* VarGrp_2* VarGrp_3* { metaregW EffectSize `var' [aw=weight] , model(ml) } ***** But, this produces lots of extraneous output (R^2, Qs, 95%CIs, etc.) since I only need the B1_coef and p-value from each run. So, I am looking for a way to either capture the target values in a table/list via a modification of the above command, or an alternative method of creating a list of the B1_coefs and p's for this problem. Any suggestions? Much thanks, Wendy * * 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/ * * 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/ * * 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/
