# Revision history [back]

Here is an example:

* Read some data.
sample 1 5
1           2        3
1      -99999        3
1           2   -99999
-99999      2        3
1           2        3

* Calculate means for the 4 observations and print them.
set skipmiss
stat var1 var2 var3 / mean=means
print means

* Set missing value to means for any variables we want.
set noskipmiss
if(var1.eq.-99999) var1=means:1
if(var2.eq.-99999) var2=means:2
if(var3.eq.-99999) var3=means:3

* Check the result. 5 Observations shown with means correct.
stat var1 var2 var3


The output is:
