DCC-GARCH model and AR(1)-GARCH(1,1) regression model
...to be done in two steps: 1) estimate the AR parameters 2) estimate the GARCH part of the model on the residuals from the AR model And this would be my rather poor idea of how to do it... library(timeSeries) library(fSeries) step1 = arma(DCCrho, order = c(1,0), include.intercept = TRUE) step1$res step11 = na.remove(step1$res) step2 = garch (step11, order = c(1,1), include.intercept = TRUE) To be honest I have no clue how to do it. I don't even now why do I get a missing value as a result of step1 (step1$res[1]) and how to account for it? Above, I just removed it but then I have a smaller num...
