Deterministic trend and stochastic trend
WebApr 16, 2024 · The "stochastic trend" terminology refers to η t. The random walk is a highly persistent process, giving its sample path the appearance of a "trend". Such processes … 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 …
