WebThe parameter estimates are close to those of the GARCH(1,1) model shown before, but there is a major difference between the two models. The unconditional variance of a t, hence that of r t, is not defined under the above IGARCH(1,1) model. This seems hard to justify for an excess return series. From a theoretical point of view, the IGARCH ... Web5.2.1 Estimation of GARCH models. ARCH/GARCH models cannot be estimated using OLS because the model is nonlinear in parameters 40 The estimation of GARCH models is thus performed using an alternative estimation technique called Maximum Likelihoood (ML). The ML estimation method represents a general estimation principle that can be applied …
