sdts_score: Computes the F-Score of a SDTS prediction
In franzbischoff/tsmp: Time Series with Matrix Profile

Description Usage Arguments Details Value References See Also Examples

Computes the F-Score of a SDTS prediction.

1	sdts_score(pred, gtruth, beta = 1)

`pred`	a `vector` of `logical`. Predicted annotation from `sdts_predict()`
`gtruth`	a `vector` of `logical`. Ground truth annotation.
`beta`	a `numeric`. See details. (default is `1`).

beta is used to balance F-score towards recall (>1) or precision (<1).

Returns a list with f_score, precision and recall.
