Subject   st: Cholesky decomposition of residuals covariance matrix after xtmixed
Date   Fri, 3 Dec 2010 17:58:16 -0000

Dear All,
I am running a mixed linear model using the xtmixed command and I would like
to apply a Cholesky decomposition on the covariance matrix of the model
residuals. Is this possible in STATA? Is there a workaround?

Wishes
Fotios
