WebNov 8, 2016 · Simply put GARCH (p, q) is an ARMA model applied to the variance of a time series i.e., it has an autoregressive term and a moving average term. The AR (p) models the variance of the residuals (squared errors) or simply our time series squared. The MA (q) portion models the variance of the process. The basic GARCH (1, 1) formula is: garch (1, 1 ... WebBasic model: Self-return moving average model (ARMA (P, Q)) is one of the most important models in the time series.
