I am looking for syntax to change the missing values of a variable to the average of the remaining values of the same variable

 

for example:

for the variable duration-

duration : 10 20 30 40 . . .  ( . meaning missing values )

I want to replace the three missing values with the average of 10 20 30 40. I want to repliate this over a variable having more than 1000 values.

 

Can anyone help me out ?

 

Many Thanks!

As an option, you could also do:

proc sql;
  create table WANT as
  select  coalesce(DURATION,(select mean(DURATION) from HAVE)) as DURATION
  from    HAVE;
quit;

Not having a nested clause speeds things up a bit.

 

create table WANT as
select coalesce(DURATION, mean(DURATION) ) as DURATION
from HAVE;
