Hi Matt,
I am sorry to post this basic question .
But how does this logic that you wrote work
1)(generate firsttransplant = year + (real(substr(quarter, 2, 1)) - 1) /4 if livertransplant == "yes"
2)bysort pseudoid (firsttransplant): replace firsttransplant = firsttransplant[1]
3)keep if year + (real(substr(quarter, 2, 1)) - 1) / 4 > firsttransplant
Thank you,
Yours Sincerely,
Anwar Dudekula

Hi Anwar,
How about:
generate firsttransplant = year + (real(substr(quarter, 2, 1)) - 1) /
4 if livertransplant == "yes"
bysort pseudoid (firsttransplant): replace firsttransplant = firsttransplant[1]
keep if year + (real(substr(quarter, 2, 1)) - 1) / 4 > firsttransplant
Best,
Matt
