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. Webstochastic trend (or "difference stationarity" in the parlance of Cochrane, 1988) against nearby deterministic-trend ("trend stationary") alternatives, together with the fact that such nearby alternatives are the relevant ones.
