Re: Issues with DCC-GARCH

Hmm. Thanks a lot for your help Tom. I was playing around with a DBEKK model to study the volatility spillovers between these markets and found evidence of either uni-directional (SP to Middle East) or no spillovers. I know the models are different and I'd have to alter the framing of the research s...

Re: Issues with DCC-GARCH

To answer the last question first, the process for getting correlations is the same for any type of multivariate GARCH model. See https://estima.com/docs/RATS%209%20Users%20Guide.pdf#page=328 Since you haven't gotten the model to converge, the second really can't be answered. However, note that B=1...

Issues with DCC-GARCH

Hello, I am new to RATS and so far I am finding it pretty nice compared to other software I have used. I have three questions regarding DCC-GARCH and would be more than grateful for any help. First, when estimating the model on some equity returns, I believe the estimation is getting stuck in a non-...

Hello Tom, Thank you for your prompt response. I have already tried putting a space but I am getting the same error: dec vect[series] sept92virf(3) do i=1,3 set sept92virf(i) 1 nstep = 0.0 ## SX22. Expected Type INTEGER, Got REAL Instead >>>>t92virf(i) 1 nstep <<<< The above is literally copied and ...

Replicating Hafner and Herwartz (2006) VIRFs

Hello, This is my first time using RATS so please excuse what I think is a very simple question. I am currently trying to follow the VIRF manual attached. Everything works up until the point where I enter: dec vect[series] sept92virf(3) do i=1,3 set sept92virf(i) 1 nstep=0.0 I keep getting the error...
