The ado-file --sutex-- (has to be installed by typing --findit sutex-- into the Stata command window) provides a simple way to export summary statistics from Stata to a separate LaTeX-file. It is limited in individualised adjustment, but quite OK for most applications. By default, you get mean and standard deviation for variables VAR1, VAR2, VAR3, etc. A syntax could be:

sutex VAR1 VAR2 VAR3, lab nobs key(descstat) replace ///
file(descstat.tex) title("Summary statistics") minmax

with the following options included:
— lab (use labels instead of variable names)
— nobs (add number of observations
— key(STRING) (add a key to the table so that you can reference from the text by typing \ref{STRING} in the LaTeX file)
— file(STRING) (generates a new .tex-file)
— title("STRING") (adds a title to the table)
— minmax (adds minimum and maximum)
— replace (replaces the old file when there was a new run)

The new .tex-file (here: descstat.tex) can be easily included into another .tex-file by using the LaTeX-command: \input{descstat}

Alternative (manual) way:

quietly: tabstat VARLIST, c(s) stat(mean) save
matrix output = r(StatTotal)'
quietly: tabstat `desc', c(s) stat(sd) save
matrix output = output,r(StatTotal)'

outtable using TEXFILENAME, mat(output) center replace ///
caption("TITLE") nobox f(%12.2fc) label ///
clabel(descstat)

NOTE: before using this alternative approach, you have to install the ado-file —outtable–. In the field --stat(mean)-- you can enter any statistic generated by stata (count, sd, min, max etc)
