WebFirstly, it may be hard to identify multiple structural breaks in the deterministic trend when the sample size is small. Secondly, implementing endogenous multiple structural break tests is a demanding exercise. Therefore, using stochastic trends sometimes instead of … 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.
