Hi
Could someone explain correlation in SAS with example and syntax.
Thanks
Using the SASHELP.CLASS data set, say you wonder if height and weight are correlated. One could expect that.
PROC CORR DATA = SASHELP.CLASS;
VAR WEIGHT HEIGHT;
RUN;
Then you get an output like this:
Pearson Correlation Coefficients, N = 19
Prob > |r| under H0: Rho=0
Weight Height
Weight 1.00000 0.87779
<.0001
Height 0.87779 1.00000
<.0001
That at the very least it's telling you that the (pearson) correlation is 0.88.
There is also plenty of documentation here:
Base SAS(R) 9.2 Procedures Guide: Statistical Procedures, Third Edition
Best of luck.
