Hi Dimitry, that's great! Thank you very much!
I tried to implement your command; however, I get an error as it says:
variable Var* not found
r(111);
Might it depend on the fact that I start your procedure from here:
levelsof listA, local(listA)
as I already have my dataset ready for calculation)?

Oggetto: Re: st: replacing with mean
Fabio,
Nick's suggestion can be implemented in the 2nd loop below:
************************************************************
clear all
set more off
/* Fake Data */
set obs 26
gen str1 industry=""
local c=1
foreach l in `c(ALPHA)' {
replace industry = "`l'" in `c'
local ++c
}
expand 27
sort industry
forvalues v=1/20 {
gen Var`v'=round(uniform()*`v',1)
}
gen listA=_n
/* Actual Loop */
levelsof listA, local(listA)
foreach var of varlist Var* {
qui gen `var'_med=.
foreach firm in `listA' {
qui gen inc=cond(listA != `firm',1,.)
qui egen med=median(`var'*inc), by(industry)
qui replace `var'_med=med if listA==`firm'
qui drop med inc
}
}
