ARIMA(0,0,0)x(0,1,0): Seasonal random walk model - Duke …

Web7 gen 2024 · This formula is the same as the generalised ARIMA (0,1,1) apart from the θ_0 term. This is a constant though, and a constant can be zero. Therefore, SES can be said to be equivalent to an ARIMA (0,1,1) model without a constant (i.e. θ_0 = 0), where α = 1 - θ_1. Hope this helps!

The forecast for a random walk is its last observed value, regardless of the forecast horizon. The forecast for an MA (1) process is nonzero only for horizon h = 1. Thus you get a constant forecast (equal to the last observed value plus one value of MA (1) term) beyond h = 1. detox max sirup kako se koristi
