Prompt: 10.24 The choice of the smoothing constants, α and β, has a considerable effect on the accuracy of the forecasts obtained by using exponential smoothing with trend. For each of the following time series, set α = 0.2 and then compare MAD obtained with β = 0.1, 0.2, 0.3, 0.4, and 0.5. Begin with initial estimates of 50 for the average value and 2 for the trend . a. 52, 55, 55, 58, 59, 63, 64, 66, 67, 72, 73, 74 b. 52, 55, 59, 61, 66, 69, 71, 72, 73, 74, 73, 74 c. 52, 53, 51, 50, 48, 47, 49, 52, 57, 62, 69, 74 Step 1) Change the Beta Value and create a graph for each of the 5 given Beta values in each of the 3 databases. You could also create one graph per tab with 5 separate lines. Step 2) Briefly describe the impact of the Beta value on the 3 databases.
