The correlate
command will report the correlation matrix of the data, but there are
occasions when you need the matrix stored as a Stata matrix so you can
further manipulate it. You can obtain it by typing
. matrix accum R = varlist, nocons dev
. matrix R = corr(R)
The first line places the cross-product matrix of the data in R. The
second line converts that to a correlation matrix.
