I am trying to export a table of summary statistics using the following command:

outreg2 using "results.doc", replace sum(log) keep(compost recycling inc popden hhsize) eqkeep(mean sd min max) title("Summary Statistics") ctitle(Mean, Standard Deviation, Minimum, Maximum)

I would however like to change the four column titles to Mean, Standard Deviation, Minimum and Maximum, however this command only changes the first column.
I would also like to add notes at the bottom of the table but do not know how to do this.

Any help is greatly appreciated!
