Consider the process Xt = -0.5Xt-1 + 0.06Xt-2 + &t - 0.4&t-1 where &t ~WN(0,1)
a. state the name of the process, and write the parameters, b. examine the stationarity and invertibility of the processes C. If it is invertible, write the process in Inverted Form. d. If it is stationary, write the process in Random Shock Form
