The mean of absolute errors between real values and predictions.

MAE(Y, Ypred)
``` |

`Y` |
a real vector with the values of the output |

`Ypred` |
a real vector with the predicted values at the same inputs |

a real which represents the mean of the absolute errors between the real and the predicted values:

*MAE = 1/n * [|Y(x1)-Ypred(x1)|+...+|Y(xn)-Ypred(xn)|]*

where *xi* denotes the points of the experimental design, *Y* the output of the computer code and *Ypred* the fitted model.
