Compute Mean Absolute Gross Error of observed and predicted data.
Usage
mage(obs, pred, use = "everything")
Arguments
- obs
A numeric vector, data.frame or data.table.
- pred
A numeric vector, data.frame or data.table.
- use
An optional character string giving a method for computing index of agreement
in the presence of missing values. This must be one of the strings
"everything" or "complete.obs".
Value
The Mean Absolute Gross Error of input data as a numeric value.
Details
Compute Mean Absolute Gross Error of observed and predicted data according to the
following definition:
$$
\mathrm{MAGE} = \sum_{i=1}^{N} \frac{|P_i - O_i|}{O_i}
$$
Examples
if (FALSE) { # \dontrun{
validationData[, .(mage = mage(obs, mod, use = "complete.obs"))]
} # }
