SCENARIO 16-13 Given below is the monthly time series data for U.S.retail sales of building materials over a specific year. The results of the linear trend, quadratic trend, exponential trend, first-order autoregressive, second-order autoregressive and third-order autoregressive model are presented below in which the coded month for the month is 0: Below is the residual plot of the various models:
-Referring to Scenario 16-13, what is the exponentially smoothed forecast for the month using a smoothing coefficient of W = 0.5 if the exponentially smooth value for the 1 and 11th month are 9,746.3672 and 9,480.1836, respectively?
