Re: Correlation in SAS

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.
