Usage
binary_roc_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 false-positive and true-positive rates.
Examples
binary_roc_curve(c(0.1, 0.8, 0.7, 0.2), c(0, 1, 1, 0))

#> 1 Inf 0.0 0.0
#> 2 0.8 0.0 0.5
#> 3 0.7 0.0 1.0
#> 4 0.2 0.5 1.0
