Two different forecasting techniques were used to forecast demand for case sets of forecasts for seven periods are as follows: a-1. Calculate the MAD for each set of forecasts, (Rio und the final nnawers to 2 docimal places.) a-2. Which technique appears to be more accurate? b-1. Calculate the MSE for each set of forecasts. (Round the final answers to 2 clecimal places.) b-2. Which technique appears to be more accurate? c-1. Calculate the MAPE for each set of forecasts. (Round the finol answers to 2 decimal ploces.) Two different forecasting techniques were used to forecast demand for cases of bottled water in a store. Actual demand and the two sets of forecasts for seven periods are as follows: a-1. Calculate the MAD for each set of forecasts, (Round the final answers to 2 decimal placee.) 0-2. Which technique appears to be more accurate? b-1. Calculate the MSE for each set of forecasts. (Round the final onswers to 2 decimal places.) b-2. Which technique appears to be more accurate? b-2. Which technique appears to be more accurate? c-2. Which technique appears to be more accurate? d-1. Do all three of forecast errors provide the same conclusion (i.e., are they consistent) in this case? d-2. Do you expect consistent results in every case? will have lower MSE than if obs 7 for F1 was 80. e, in practice, either MAD, MSE, or MAPE would be employed to compute a measure of forecast errors.
