Hello all, here is what I have

YearVarValue
20003
20005
2000
200010
20017
20012
2002
20029
2002
20042
2004

I would like to impute the missing values of VarValue for each year with the minimum VarValue for that year. Something like this below. A datastep would be preferable as I do not know SQL (but I am not opposed to SQL as long as I can modify it easily). Thanks!!

Here's one fairly standard way to use a DATA step:

data want;

   do until (last.year);

      set have;

      by year;

      minimum_value = min(minimum_value, VarValue);

   end;

   do until (last.year);

      set have;

      by year;

      if VarValue=. then VarValue = minimum_value;

      output;

   end;

   drop minimum_value;

run;

Here's the SQL way.

proc sql;

create table want as

select a.year, a.varvalue, min(a.varvalue) as min, coalesce(a.varvalue, calculated min) as new_varValue

from want a

group by year;

quit;
