Web7.1.2 Stochastic and Deterministic Trend. There is a distinction between deterministic and stochastic trends. A deterministic trend is a fixed function of time. If a series has a deterministic trend, the increase (or decrease) in the value of the series is a function of time. For instance, it may appear to grow or decline steadily over time.
WebThis process shows both a deterministic trend and a stochastic trend. Using the general solution for the previous process, y t= y 0 + at+ Xn t=1 t where y 0 + atis the deterministic trend and P n t=1 tis the stochastic trend. The relevance of the random walk model is that many economic time series follow a pattern that resembles a trend model. Web2t with deterministic trends Even after removing a determinist trend from y 1t, the residuals still behave like a random walk. On the other hand, y 2t is de nitely trend-stationary.
