{{alias}}()
|
||
|
|
Returns an accumulator function which incrementally computes the mean
|
||
|
|
absolute percentage error (MAPE).
|
||
|
|
|
||
|
|
If provided input values, the accumulator function returns an updated mean
|
||
|
|
absolute percentage error. If not provided input values, the accumulator
|
||
|
|
function returns the current mean absolute percentage error.
|
||
|
|
|
||
|
|
If provided `NaN` or a value which, when used in computations, results in
|
||
|
|
`NaN`, the accumulated value is `NaN` for all future invocations.
