WebTechnically you may have GARCH (1,2) with the coefficient on σ t − 1 2 being equal to zero (similarly, there is nothing wrong with ARMA models that have some zero coefficients). It is a matter of how well the model approximates the data, and apparently GARCH (1,2) does a better job that its competitors for your data. Share. WebThis example shows how to compare two competing, conditional variance models using a likelihood ratio test. Step 1. Load the data and specify a GARCH model.
