Hi, Is there a way SAS allows to do a mean across varaibles (and use a BY statement).
Here's what I mean:
HAVE:
Prod Price1 Price2 Price3 Price4
A 2 4 7 6
B 3 . 5 3
C . 5 . .
D . . . .
WANT: If I want the MEAN of the last 3 Prices & last 4 Prices
Prod Month3_Prices Month4_Prices
A 5.6 4.7
B 4 3.6
C 5 5
D . .
I tried different variations of Proc MEAN, couldn't get it, but I'm sure there is a simple way.
Thanks
I think I got it.. using:
avg=Mean(of x y z);
Yes, except you can do mean(of price1--price3) and mean (of price1--price4) as well as mean(price1, price2, price3) and mean(price1, price2, price3, price4)
Well, it may not be everyone's idea of fun, but here's a program you can play around with ... "just for fun".
data _null_;
p1=1;
p3=3;
p2=4;
of=20;
m1 = mean(of p1--p3);
m2 = mean(of p1-p3);
m3 = mean(of p1 p2 p3);
m4 = mean(of p1,p2,p3);
m5 = mean(of,p1,p2,p3);
put m1= m2= m3= m4= m5=;
run;
