sdts_score: Computes the F-Score of a SDTS prediction

Description

Computes the F-Score of a SDTS prediction.

Usage

sdts_score(gtruth, pred, beta = 1)

Arguments

gtruth

a vector of logical. Ground truth annotation.

pred

a vector of logical. Predicted annotation from sdts_predict()

beta

a numeric. See details. (default is 1).

Value

Returns a list with f_score, precision and recall.

Details

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