I have been experimenting with univariate GARCH regressions. I have found
the abarch/sdgarch/tarch variants to work well on my data.
I'd like to apply these variants to a multivariate GARCH setting. However,
only the basic arch and garch options seem to be available, based on my
reading of the official Stata documentation.
Is there a way to apply the capabilities of the univariate arch to the
multivariate setting? a clever hijacking or copy-pasting blocks of code
from the ado files ... any suggestions?
