From: clyde013 on 15 Mar 2010 16:14 Hello, I have a data set similar to the following: dummy NJ NH 0 3 7 0 7 8 0 6 9 1 4 6 1 5 7 1 6 3 proc ttest data=sum; paired nj*nh; run; I would like to do a paired t-test because NJ and NH are dependent. But I need to compare them by the dummy variable. In a regular t-test I would use a class dummy statement but I cannot use a class variable in a paired t-test. Is there an alternative way to calculate a paired t-test?
