T/F The expected value of a random walk is dependent on time. Note: Make sure you understand what a random walk is! Think of the drunken man. - False. X_t = X_(t-1) + W_t, where W_t ~ Normal(0,V). T/F A moving average process is a linear process. - True. T/F If X_t is a stationary time series, then -Xt must be a non-stationary time series. - False. Taking the negative of the series does nothing to affect trend, variance, or add autocorrelation, and thus the process remains stationary. T/F...
