st: Using mysureg with svy

[Jennifer Cornman <jencornman@gmail.com>]

Hi,

I am running seemingly unrelated regression models using the command
mysureg so that I can also use the svy prefix to account for the
complex survey design of my data. I have two outcomes and each model
contains exactly the same predictors. I am interested in the
correlation between the model residuals. However, when I use the svy
prefix, the output from the mysureg command does not include the
residual correlation matrix. I was wondering whether anyone might know
why the residual correlation matrix does not get produced when mysureg
is used with svy. Also, if I were to run the same models using mvreg,
the output includes both the residual correlation matrix and a
Breusch-Pagan test of independence. The mysureg command does not
produce the same test and I was wondering why this might be.

I appreciate any thoughts on these issues.

Thanks,

Jennifer Cornman
