This raises an important related issue. Does anyone know of or have a
Stata program for ML estimation (assuming multivariate normal) of a
covariance matrix using all the data, even if some vectors have missing
components?

Dear Listers,
Bill Gould in 1999 answered the question of how to store pairwise
correlations of a varlist in a matrix--basically calculate the
covariance matrix and then convert it into a correlation matrix. The
problem with that answer is that it does not use all the data--basically
the difference between -corr-and -pwcorr-. Does anyone have a better
answer, one that uses all the data, like -pwcorr- does?
Thanks,
m.p.
