Mean absolute error - Wikipedia
https://en.wikipedia.org/wiki/Mean_absolute_error
WEBIn statistics, mean absolute error ( MAE) is a measure of errors between paired observations expressing the same phenomenon. Examples of Y versus X include comparisons of predicted versus observed, subsequent time versus initial time, and one technique of measurement versus an alternative technique of measurement.

WEBMean Absolute Error. The Mean Absolute Error(MAE) is the average of all absolute errors. The formula is: Where: n = the number of errors, Σ = summation symbol (which means “add them all up”), |x i – x| = the absolute errors. The formula may look a little daunting, but the steps are easy: Find all of your absolute errors, x i – x.
