WebMar 14, 2024 · Deterministic and stochastic trends have different implications for forecasting. Deterministic trends have a constant variance throughout time. In the case of a linear trend, this implies that the slope will not change. But, real-world time series show complex dynamics with the trend changing over long periods.

"WebTime series with a stochastic trend never recover from shocks to the system (the effects of shocks are permanent). Forecast intervals grow over time. Unfortunately, for any finite amount of data there is a deterministic and stochastic trend that fits the data equally well (Hamilton, 1994). " - Deterministic trend vs stochastic trend
