Multiple Correlations and Multicollinearity
 

I was wondering if there is a way to get excel to run correlation test
between every combination of 37 or 38 independent variable. I need to
find the best way to reduce multicollinearity, and finding every
possible correlation would give me the best idea of which direction to
take. I know the actual computation would take quite a while, but the
computer that would run the tests is very fast, so even 38! runs
shouldn't take very long.

I was also wondering if there was a way to find correlation between one
independent variable and every possible combination of the others,
although this would take much more computing time and might not even
be necessary.

Any guidance is appreciated!

That sounds like something you need a statistics package for.

Multiple Correlations and Multicollinearity
 

Which are the best packages? Do you think they can run multiple
correlation tests over several columns, or would I need to find a macro
to do that?

Thanks for your response.

Also, I know Excel has a correlation function, so the only difficulty is
automating it to run and rerun the test over a range. If you think there
is a way to do so with a macro or otherwise, please let me know.
