Hi, I'm having problems using outreg2 to export the results from a Heckman model to LaTeX (same problem occurs when exporting to a .doc file). The following code produces a hypothetical Heckman model and exports the results to LaTex. For some reason, the 3rd column replicates the 2nd column. I would like to only keep column 1 and 2.

A similar problem, but no solution, was posted here: https://www.statalist.org/forums/for...ach-regression

clear
input yvar xvar1 xvar2
3 2 1
4 0 3
. 3 1
. 1 2
2 7 0
6 0 1
. 3 7
0 1 1
. 2 2
1 1 5
end

heckman yvar xvar1 xvar2, select (xvar1 xvar2) vce(robust) iterate(10)
outreg2 using "test_outreg2.tex", replace tex(pretty) keep(xvar1 xvar2)
