What is the similar of the use of MAD and MSE in evaluating forecasts
Solution
4
MAD = Mean Absolute Deviation MSE = Mean Squared Error
I\'ve seen suggestions from various places that MSE is used despite some undesirable qualities (e.g. http://www.stat.nus.edu.sg/~staxyc/T12.pdf, which states on p8 \"It is commonly believed that MAD is a better criterion than MSE. However, mathematically MSE is more convenient than MAD.\")
Is there more to it than that? Is there a paper that thoroughly analyzes the situations in which various methods of measuring forecast error are more/less appropriate? My google searches haven\'t revealed anything.
