WebOne type of trend is produced by a trend-stationary (TS) process, which is the sum of a deterministic trend and a stationary process. TS variables, once identified, are often linearized with a power or log transformation, then detrended by regressing on time. ... Stochastic Trends. Not all trends are TS, however. Difference stationary (DS) ... Web9.4 Stochastic and deterministic trends. 9.4. Stochastic and deterministic trends. There are two different ways of modelling a linear trend. A deterministic trend is obtained using the regression model yt …
