You mean that i have to also write set ect1 = 100*log(fra/ger) set ect2 = 100*log(ger/ita) set ect3 = 100*log(ita/uki) set ect4 = 100*log (fra/ita) set ect5 = 100*log (fra/uki) set ect6 = 100*log (ger/uki) in order to have the equation meaneq * # constant y(1){1} y(2){1} y(3){1} y(4){1} ect1{1} ect2...

Re: MV-EGARCH with spillovers

Dear Tom,
i follow Koutmos code to estimate the spillover among 4 countries but instead of a var - egarch model i have to estimate an ecm multvariate egarch model.
What should i add in this code so as to estimate the ecm-mv-egarch ?

Thank you very much

I am trying without result to insert the data into the rats from an excel sheet. The data are monthly and i follow the routine: d...
