Three popular measures of forecast accuracy are:

a) total error, average error, and mean error.

b) average error, median error, and maximum error.

c) median error, minimum error, and maximum absolute error.

d) mean absolute deviation, mean squared error, and mean absolute percent error.

a) standard error of the estimate.

b) cumulative error.

c) mean absolute deviation (MAD).

d) ratio of the cumulative error to MAD.

e) mean absolute percent error (MAPE).
