Assuming your week is integers
 gen newweek=cond(abs(round(week,12)-week)<=2,round(week,12),week)
should do.

Hi listers,
I want to round a variable 'week' if it is within 2 weeks range of 
multiples of 12 week. So 10 weeks should become 12 weeks while 9 weeks 
should not change. Similarly 21 weeks would not change while 25 weeks 
will change to 24 weeks. Is there a way to do it in Stata using -round- 
or other command?
Thank you,
Shehzad
