Integrated DCC GARCH

Unread post by gemmamc88 »

Hi,

I was just wondering if it is possible to adapt the code for the GARCH estimation of DCC or can you only do it with two step likelihood?

I have used the code:
garch(p=1,q=1,i=nodrift,model=ar1,mv=dcc,asymmetric,pmethod=simplex,piters=100,method=bfgs,iter=1000,trace)

with ar1 representing my system of mean equations.
In my understanding the i term and asymmetric commands relate only to the volatility and not to the correlation.
However the sum of my a and b DCC coefficients is 0.99 suggesting the need for an integrated DCC GARCH and I was wondering how to perform this.

Thanks for your help. The RATS support services are excellent.

The GARCH instruction won't do DCC with an integrated DCC model. You'll have to modify one of the examples on http://www.estima.com/forum/viewtopic.php?f=11&t=792 to incorporate the restriction.
