I'm trying to do regression analysis on a large number of variables and use those results to cull most of those and leave myself with just 15-20. Unfortunately, when using my program, Stattools, the regression is halted because some of the variables have exact multicollinearity. The program won't tell me which ones. Should I not be able to identify them by checking for correlation between the variables? When I ran a correlation table, all I saw was the standard diagonal of 1.000 correlations between variables and themselves, and no 1.000 correlations with any others. If that doesn't work(it didn't when I tested a variable's correlation with its log transformation), are there any other tests I could run to identify these?
