This will give you four separate csvs and open them:

Betreff: Re: st: AW: Formatting tables with estpost & esttab
Hi Martin,
I tried to loop the code applying estpost&esttab over several
variables, but no success yet. Below is the code.
The idea is to save into Excel for further manipulation.
----------------------------------------------------------------------------
-------
sysuse auto, clear
xtile price3= price, nq(3)
xtile weight3= weight, nq(3)
xtile mpg3= mpg, nq(3)
tempname hdle
capt erase info.dta
postfile `hdle' str10 var n1 colperc1 /*
*/ n2 colperc2 pval overalln overallcolperc /*
*/ using info
foreach var of varlist rep price3 weight3 mpg3{
estpost tab `var' for, chi2
eststo
esttab *, main(b) aux(colpct) nostar unstack noobs nonum nonote
sca("chi2 Chi2 Value" "p corr. p-value") sfmt(%4.3fc) wide compress,
using example.csv, replace
}
postclose `hdle'
use info, clear
l, abbrev(12) noobs sep(0)
----------------------------------------------------------------------------

Thank you in advance,
