Web14 dic 2024 · 1 Answer Sorted by: 2 Arima () fits a so-called regression with ARIMA errors. Note that this is different from an ARIMAX model. In your particular case, you regress your focal variable on three predictors, with an ARIMA (1,1,1) structure on the residuals: y t = β 1 x 1 t + β 2 x 2 t + β 3 x 3 t + ϵ t with ϵ t ∼ ARIMA ( 1, 1, 1). 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.
