Garch filter
Web$\begingroup$ I guess this is because the suggested autocorrelation in residuals, which are mentioned in the original question, usually is not a problem when using GARCH, which should be obvious, since the volalatility equation of the GARCH model is an ARMA-model of the residuals, which will usually be able to filter any autocorrelation of the ...
