st: Using outreg2 within a loop

[Suryadipta Roy <sroy2138@gmail.com>]

Dear Statalisters,

I am using the following form of code to get the regression results
within a table using -outreg2- :

forvalues i = 1(1)5 {
xttobit dep_var `controls' if period == `i', ll(0)
outreg2 using "C:\file.doc", nocons tstat dec(2) bracket keep(var1
var2) addstat(Adj. R-squared, e(r2_a)) word label `append'
local append "append"
}

When the file gets saved, two separate columns for "sigma_u" and
"sigma_e" are added for each of the five regressions. While I can
delete the columns manually, I was wondering if there is a suggestion
as to how to prevent them from appearing in the first place. Any
suggestion is greatly appreciated.


Sincerely,
Suryadipta.
