Is there a way to transfer a correlation matrix directly into a matrix

something like - mat def Rx = -

Does stata have an ado file that does regression with correlation
coefficients (a la SPSS)?

That is, I would generate the standardized betas something like

-mat def b=inv(Rx)*Ry   where Rx is the matrix of correlations among
Xs and Ry is the vector of correlations with Y.
See pages 8-10 of

or else possibly

The first shows you how to analyze a correlation matrix when you don't have the original raw data, e.g. you are working from a printed article. The 2nd shows you how you can use matrix functions to create a correlation matrix and do your own regression analysis.

Incidentally, -regi- (where i = immediate) would be a logical command for Stata to have, given that it has other immediate commands (e.g. -ttesti-), but as far as I know no one has written it.
