Can I do this in PROC CORR? I tried to create 6 dummy variables and get a Pearson value but is it real?<BR /> <BR /> Thx Tue, 26 Oct 2010 17:49:23 GMT https://communities.sas.com/t5/SAS-Procedures/Class-variables-in-PROC-CORR/m-p/23037#M5043 deleted_user 2010-10-26T17:49:23Z https://communities.sas.com/t5/SAS-Procedures/Class-variables-in-PROC-CORR/m-p/23038#M5044 As far as I know, there is no such thing as a correlation with a classification variable.<BR /> <BR /> You probably want to think more about what outputs make sense to you here. For example, might you want to compare the means at each of the six levels of the classification variable?
