Webdepends on whether the trend is deterministic or stochastic. If a trend is stochastic, we di erence the data to isolate the stationary component. The process is di erence-stationary. In the case of a random walk with drift, we have E( y t) = E(a 0 + "t) = a 0 var( y t) = E( y t 2a 0)2 = E(" t) = ˙2 cov( y t; y t s) = E(" t;" t s) = 0 If the ...
