how to estimate likelihood ratio in restricted MVgarch

Unread post by hardmann »

Dear Tom:

While I estimate a MVgarch model, I could do wald test by using "restrict" or "test" command.
However, how could I get Likelihood ratio throgh comparing restricted and unrestric model.

MAXIMIZE and GARCH both define the %LOGL variable. Estimate one model, save %LOGL, estimate the other, and do a test on the difference. The PROBIT.RPF example does this for a probit model.
