Shannon Driver has developed the following ado-file: zscore. You can get it
from the command window by typing: net install zscore. It does the
z-transformation for you. After the transformation, you can use the recode
command.

Emne: st: Create categorical variable based on 'z-score'
Generic problem: I'd like to create categorical variables for a list of
continuous variables. The categorical variables would be based upon the
z-score of each variable, such as:
Z-score of X catX
<-2 -3
-2 ..-1 -2
-1 .. 0 -1
0 0
0.. +1 +1
1 ..2 +2
>+2 +3
If there were a way to z-transform variables, I could do an easy
recode(catX)
Thanks!
