As always with the "greater than" operator in Stata, special care should be
taken with regard to missings. So my expanded advice for you would be to
explicitly account for them:
*************
clear*
set obs 10000
gen var=runiform()
su var
//introduce missings
replace var=. in 5/8
ins var
//explicity deal with missings
gen byte newvar=var>.5 & !mi(var)
ta newvar, mis
l in 1/10, noo
*************

Betreff: st: recoding a variable
Hi,
I got some very good quick advice on a looping question I asked
earlier. I have another question. Suppose I have a variable with
values that range between 0 ands 1. I simply want to recode this so
that any value greater than 0.5 becomes a 1, and 0 otherwise. How do I
do this?
Thanks,
Walt
