Using xtile for a subset of cases

[Al Bothwell]

I tried to use xtile with the if statement, but received the message, "option if not allowed". Is there a workaround?

xtile risk_cat3=riskscore, nq(3) if sOTcat==1

Al:
what if you impose a minor trick to your previous code?

xtile risk_cat3=riskscore if sOTcat==1, nq(3)

Thank you Carlo. Your code worked perfectly!
