Hi Caliph,

you could use the estadd command which is part of estout to get e-class results.
Example:

webuse fuel2
ranksum mpg, by(treat)
ret li
estadd scalar N_2 = r(N_2)
eret li

Best, Carsten

Thank you Nick
I never programmed and it seems complicated than i thought.

0. Read the chapters on [U] on programming until you understand enough
to get your program working correctly.

1. Your program will allow syntax like the r-class command, but will
be declared as e-class.

2. Your program will run the r-class command.

3. Your program will pick up the r-class results you want and return
them as e-class results.

Here is a toy example:

program mymean, eclass
                 version 9
     syntax varname(numeric) [if] [in]
     marksample touse
     qui count if `touse'
     su `varlist' if `touse', meanonly
     ereturn scalar mean = r(mean)
end

If you have never programmed in Stata before, expect this to take
several hours.

Naturally, it might be easier to work out how to format results you
save otherwise within your word processing software (at a guess, MS
Word).

You could always write "your own" eclass version of the program.  I've had to do this for folks before and I just ended up posting the results from -r()- into -e()- with the same name.  Then esttab/estout works fine.

-eststo- and -estpost- are user-written commands (SJ, SSC), as you are
asked to explain.

You don't show the code you tried using -eststo- or -estpost- (or I
gather other commands) but as -ranksum- is not an estimation command,
I don't think you should expect your code to work. The difference
between e-class and r-class commands is crucial here.

Others may have positive suggestions.

I am having a problem of how to export  Mann-Whitney U Test output into rich text format "rtf"
I tried to combine command like "eststo" "estpost" and the other but it is not working.
my command is listed below, what command shall i combine to export outputs including  obs;  rank sum;    expected; z and others statistics.

If you know how could you please help me?
