Export summary statistics

[Ed Suh]

Hi,

I would like to export summary statistics and have some difficulties in format.
I want to keep the 'YEAR' in the columns and the outcomes by group in the rows

* Example generated by -dataex-. To install: ssc install dataex
clear
input float score byte urban float year
85.75 1 2006
59.24 1 2006
65.92 0 2006
79.75 0 2006
  .22 0 2006
68.81 1 2006
41.06 1 2006
95.59 0 2006
 8.44 0 2006
52.04 0 2006
62.77 0 2006
end

This is the code I used:

egen group = group(urban year), label
estimates clear
estpost tabstat score_percentile, by(group) statistics(mean sd) columns(statistics) listwise 
esttab using "score_percentile_urban.tex", main(mean) aux(sd) nostar unstack noobs nonote nomtitle nonumber

I think I have to change the 'columns' but it didn't export anything to tex.

Thank you so much in advance.
