Mean Abosolute Error

Description

Given the observed and predicted values of numeric data computes the Mean Abosolute Error.

Usage

mae(observed, predicted, remove_na = TRUE)

Arguments

observed	(numeric) The observed values. It has to have the same length as predicted.
predicted	(numeric) The observed values. It has to have the same length as observed.
remove_na	(logical(1)) Should NA values be removed?. TRUE by default.

Details

Mean Absolute Error is computed as:

where y_i is the observed value of element i, haty_i is the predicted value of element i and N is the total number of elements.

Value

A single numeric value with the Mean Abosolute Error.
