Consider the time series with nine periods of data: 34, 38, 46, 41, 43, 48, 51, 50, 56 a) Use exponential smoothing to forecast the value for period 10 when = 0.2. then Calculate MAD and MAPD b) Use exponential smoothing to forecast the value for period 10 when and compared to = 0.5 then Calculate MAD and MAPD c) Compare your results for = 0.2. = 0.5 which forecast is better and why?
