WebTime series-(ARMA-GARCH) In the real world, the return processes maybe stationary, so we combine the ARMA model and the GARCH model, where we use ARMA to fit the mean and GARCH to fit the variance. For example, ARMA(1,1)-GARCH(1,1) X t = μ + φ X t − 1 + ε t + θε t − 1 ε t = σ t Z t σ t 2 = α 0 + α 1 ε t − 1 2 + βσ t − 1 2 33 http://www.ccsu.financect.net/FTC205/BFR0920Papers/502-1452-1-PB.pdf
