Hello all,
I have 60 variables called smon97-smon156 that each correspond to the
month of the year from 1986-2004 (So smon97 is jan 94 and smon156 is dec
98).
I also have a variable mondx, that was created by taking the month of
diagnosis and converting it to match the numeric part of the
mon1-mon228. I used the following command for this step: gen mondx=
((yeardx-1986)*12) + (monthdx)
So far so good. Now I would like Stata to use the mondx and refer to
the value of the corresponding smon97-smon156. I only want to keep them
if that value=3.
I have been trying to use;
gen OK=.
forvalues i = 97/156 {
if i==mondx & (smon`i'==3) replace OK = 1
}
Stata returns a type mismatch code. Mondx and all the smon* variables
are numeric floats.
Any help would be greatly appreciated!
