Webb2 aug. 2016 · The standardized residuals are ϵ ^ t, i.e. the fitted values of ϵ t. The model assumes that the standardized errors have a certain distribution (e.g. Normal, Student- t or the like) with zero mean and unit variance. The likelihood function for the model is built using this assumption.
