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
*************

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
