I want to find the amount for the period before the
policy-period and the amount after the policy period for each ID.
data want;
input ID amount_before amount_after;
cards;
1 100 500
2 480 0
3 300 .
;;;;
run;
data want(keep=ID amount_before amount_after);
call missing(ID, amount_before, amount_after);
do until (last.ID);
set have;
by ID;
if Priod-Policy_Period = -1 then amount_before = amount;
if Priod-Policy_Period = 1 then amount_after = amount;
end;
run;
Result:
ID amount_before amount_after 1 100 500 2 480 0 3 300 .
data want(keep=ID amount_before amount_after);
call missing(ID, amount_before, amount_after);
do until (last.ID);
set have;
by ID;
if Priod-Policy_Period = -1 then amount_before = amount;
if Priod-Policy_Period = 1 then amount_after = amount;
end;
run;
Result:
ID amount_before amount_after 1 100 500 2 480 0 3 300 .
Ok. But Policy_Period is still constant for each id? and in one of the obs, Policy_Period=Period, correct?
