Learning Activity # 3 Based on the following data, complete empty cells of the table by using Exponential Smoothing method. Then, Forecast the value of Month 6 and compute the MSE index. (a =0.15 and consider the forecast of first month equal to 22). Forecast Squared observations forecast Month Real MSE Forecast error error 1 25 40 2 3 4 21 30 5 22 I F = F-1 + a(4,- - F-1) MSE n
