Deterministic or stochastic trend
WebA deterministic trend is obtained using the regression model yt = β0 +β1t+nt, y t = β 0 + β 1 t + n t, where nt n t is an ARMA process. A stochastic trend is obtained using the model yt = … WebJan 22, 2024 · Deterministic Trend Model: Y t = b 0 + b 1 *TIME + b 2 *AR (1) + b 3 *AR (2) + b 4 *MA (3) + ε t Stochastic Trend Model: Y t – Y t-1 = b 0 + b 1 *AR (1) + b 2 *AR (3) + ε t The forecast based on a deterministic model is shown by the orange line while the one based on the stochastic model is shown by the gray line.
