WebAug 11, 2024 · The new GARCH fit function is called “estimate”, which uses data to estimate the unknown parameters in the GARCH model. The output of “estimate” is a fitted model, say EstMdl. Then we may use the “infer” function with EstMdl to extract the conditional variances V. In the old “garchfit”, the output variable sigma appears to be ... garchFit: Univariate or multivariate GARCH time series fitting Description Estimates the parameters of a univariate ARMA-GARCH/APARCH process, or --- experimentally --- of a multivariate GO-GARCH process model.
