Web9.4 Stochastic and deterministic trends. 9.4. Stochastic and deterministic trends. There are two different ways of modelling a linear trend. A 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 = β0 +β1t+nt ... WebNov 1, 2024 · The foregoing exercise did not specify, but the presented example was that for a deterministic trend. Another type is a stochastic trend. A random walk process, \(y_t=y_{t-1}+\zeta_t\), represents a stochastic trend.
