WebA GARCH (generalized autoregressive conditionally heteroscedastic) model uses values of the past squared observations and past variances to model the variance at time t. As an example, a GARCH (1,1) is. σ t 2 = α 0 + α 1 y t − 1 2 + β 1 σ t − 1 2. In the GARCH notation, the first subscript refers to the order of the y2 terms on the ...
