a. Calculate the MAD for each set of forecasts. Which technique appears to be more accurate?
b. Calculate the MSE for each set of forecasts. Which technique appears to be more accurate?
c. Calculate the MAPE for each set of forecasts. Which technique appears to be more accurate?
d. Do all three measures of forecast errors provide tire same conclusion (i.e., are they consistent) in this case? Do you expect consistent results for every case? Explain.
e. In practice, either MAD, MSE, or MAPE would be employed to compute a measure of forecast errors. What factors might lead a manager to favour one?
