Hello,

The code below was in response to this question:

The code below works specifically on Columns D - H. The data I want to use this on will not always be in D - H. Is there a way to update the macro so that I can 'easily' change what columns should be used to make the correlation matrices?

Thanks,

Cheers,

JE

The code below was in response to this question:

I would like to compute correlation matrices (using CORRELATE) for each group in a worksheet. The correlation matrices should be by group (5,6,7,12,13, or 14) on columns D - H. Ideally the new sheet would be named with at least the group number.

The code below works specifically on Columns D - H. The data I want to use this on will not always be in D - H. Is there a way to update the macro so that I can 'easily' change what columns should be used to make the correlation matrices?

Thanks,

In an attempt to answer only a part of the above question I asked another, less specific one here:

Which ended up answering the whole question.
