WebJan 7, 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 - … WebAug 12, 2016 · Holt-Winters has three parameters, so it's simple, but they're basically smoothing factors so it doesn't tell you much if you know them. ARIMA has more parameters, and some of them have some intuitive meaning, but it still doesn't tell you much. State Space can be complex, but you can also explicitly model things for greater …
