WebThe error term here is not observed. So to obtain this, Box et al. Time Series Analysis: Forecasting and Control (3rd Edition), page 228, suggest that the error term is computed recursively by, ε t = y t + θ ε t − 1 So the error term for t = 1 is, ε 1 = y 1 + θ ε 0 Now we cannot compute this without knowing the value of θ.
