I'm having trouble getting this to generate. gen ecobuy = 1 ifecolbs > 0 & ecobuy = 0 if ecolbs = 0. What am I doing wrong here?

If ecolbs is nonnegative and never missing, then you can use assert 0 <= ecolbs & !mi(ecolbs) gen ecobuy = (0 < ecolbs)

gen ecobuy = (0 < ecolbs) if 0 <= ecolbs

gen ecobuy = (0 < ecolbs) if 0 <= ecolbs & !mi(ecolbs) which will set ecobuy to missing if ecolbs is negative or missing.
