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