Binary Precision-Recall Curve
Usage
binary_precision_recall_curve(x, observed = NULL, thresholds = NULL)
Arguments
- x
A binary expected prediction or numeric probabilities.
- observed
Optional observed binary outcomes.
- thresholds
Optional thresholds. By default all finite empirical
breakpoints are used.
Value
A data frame containing recall and precision.
Examples
binary_precision_recall_curve(
c(0.1, 0.8, 0.7, 0.2),
c(0, 1, 1, 0)
)
