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.
