WebMay 29, 2016 · Part of R Language Collective. 1. I have a problem with parameter estimation and forecast for a GARCH model. I have a time series of volatilities, starting in 1996 and ending in 2009. I tried to estimate the parameters with the ugarchspec and ugarchfit function: garch1.1 <- ugarchspec (variance.model=list (model="sGARCH", … Web$\begingroup$ Great question! Did not have enough time to think deeper about it, but looking forward to some answers. Under a correctly specified model, the uncertainty in the forecasts of the conditional variance will be directly due to estimation variance (imprecisely estimated parameters) but not the estimated variance of the point process (which applies …
