The total number of thousands of tons of coal produced per year over a 10-year period for a certain region is provided in the accompanying dataset. Use double exponential smoothing to determine which pairs values for a and minimize MAD for this dataset. a=0.2, =0.9; a=0.4, B-03; a=1, p=06 Click the icon to view the coal production data. Coal Production - First find the MAD for each pair of values, a and .
