| Subject | st: Correlating a variable against itself over two time moments |
| Date | Fri, 6 Aug 2010 09:29:38 -0500 |
Hi;
I have a data set that has 51 Likert Scale variables and a dummy variable for pretest/posttest. I am trying to obtain a correlation matrix in Stata for the correlations of the variables against themselves over the two time moments. For example, say I have variable P1. I want to correlate P1 from the pretest against P1 from the posttest. If anyone could provide advice on how to go about doing this in STATA, I would appreciate it. M
