I apologize to everyone for the multiple posting.
Wendy, there is a carriage return after "replace", that is not
registering on in my postings.

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

You might try something like the following. 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.
Hope this helps,

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
