WebThis shows that the lag 11 autocorrelation will be different from 0. If you look at the more general problem, you can find that only lags 1, 11, 12, and 13 have non-zero autocorrelations for the ARIMA\(( 0,0,1 ) \times ( 0,0,1 ) _ { 12 }\). A seasonal ARIMA model incorporates both non-seasonal and seasonal factors in a multiplicative fashion.
