(I cannot put in the demand data table because the table is an image, but you can come up with demand data for periods 1-9). 1. The following data points represent monthly sales for take-out meals at the UTRGV student union. You are tasked to evaluate the forecast for periods 6, 7 and 8 by following the instructions bellow. 1. Prepare data for the forecast i. Fill in values for the intercept (St) for period 4 That is, fill in S4 by using a MA(3) of the previously observed data. ii. Fill in values for the slope (G+) for period 4 1. Fill in G4 by using 20% of S4. 2. Calculate the forecast for periods 6, 7 and 8 with double exponential smoothing by using Holt's method with a (-step-ahead forecast with a = 0.2 and = 0.1. Show the equations and calculations for credit or equations in your spreadsheet. 3. Calculate the mean absolute deviation (MAD) for your forecasts, and comment on the forecast.
