Consider the random walk process given by Y = Yt-1 + t, where &+ is a white noise process with variance given by the constant 8. Under the assumption that all observations of Y, and & prior to time-period 1 are exactly zero, it is reasonably straightforward to show that the variance of Y, is given by, E(Y = EY) = o. E(Y-EY+) Is the random walk process stationary? Please briefly discuss using the equation above.
