If Xt and Ytϕ1 are independent AR(1) processes, then Xt+Yt ϕ1 is an AR(2) process. - ANSWER-False. (The order of the sum of two independent AR processes is not necessarily the sum of each individual processes' order.) Let Wt be a white noise process. Then Xt=Wt−Wt−1 is stationary. - ANSWER-True An ARIMA(p,0,q) model is always stationary. - ANSWER-False There is no auto-correlation in an ARIMA(1,d,q) process. - ANSWER-False A white noise process has zero auto-covariance for all lag...

ISYE 6402 UPDATED Exam Questions and CORRECT Answers If the time series YtYt can be represented as trend plus Gaussian white noise with Yt=βt+ϵtYt=βt+ϵt , then its expectation is E( Yt ) = β. - Ans False. It would be E(Yt) = E(βt) + E(εt) = βt + 0. If {Xt} is a stationary process, then its autocorrelation function has an expected value of 0 for lag values greater than 0. - Ans Tru
