3.(5 points) Suppose you estimated an autoregressive distributed lag model for time series dataset and obtained following result: Y = 1.3+0.4Y-1 +2.5X, +0.2.X-1+u then, which of the following arguments are correct A. The coefficients in front of the Xs are the dynamic multipliers B. The regression result suggests the dependent variable Y is nonstationary C. The first dynamic multiplier equals to 2.5 D. The long-run cumulative dynamic multiplier equals to 4.5
