For the random-walk-with-drift model, the k-step-ahead forecast from period n is: n+k n Y = Y + kdˆ ˆ where . dˆ is the estimated drift, i.e., the average increase from one period to the next. So, the long-term forecasts from the random-walk-with-drift model look like a trend line with slope . dˆ ,

It is easy to see that for i > 0 It then follows that E [y i] = y 0 + δi, var (y i) = σ2i and cov (y i, y j) = 0 for i ≠ j. The video demonstrates graphs for random walk, random walk with drift, and trend stationary process in R. Random walk with drift xt = δ + xt-1 + wt where {w t} is a white noise process, and x0 = 0.
