You could modify -_growmean- to include a multiplicative factor. For
example:
*! version 1.0.0 05jan2007
*! Based on _growmean
program define _growmean2
version 9, missing
gettoken type 0 : 0
gettoken h 0 : 0
gettoken eqs 0 : 0
syntax varlist(min=1) [if] [in] [, BY(string) factor(real 1.0)]
if `"`by'"' != "" {
_egennoby rowmean() `"`by'"'
/* NOTREACHED */
}
tempvar NOBS touse g
mark `touse' `if' `in'
quietly {
gen double `g' = 0 if `touse'
gen long `NOBS' = 0 if `touse'
tokenize `varlist'
while "`1'"!="" {
replace `g' = `g' + cond(`1'>=.,0,`1') if `touse'
replace `NOBS' = `NOBS' + (`1'<.) if `touse'
mac shift
}
gen `type' `h' = (`g'/`NOBS')*`factor' if `touse'
}
end
