Computes the Wilcoxon-Mann-Whitney AUC statistic from prediction scores
at presence and absence sites. Also returns max-Kappa and its threshold.
Usage
maxent_auc(presence, absence)
Arguments
- presence
Numeric vector of prediction scores at presence sites.
- absence
Numeric vector of prediction scores at absence sites.
Value
A named list with elements:
- auc
AUC value in [0, 1]
- max_kappa
Best Cohen's Kappa found
- max_kappa_thresh
Threshold at best Kappa
Examples
result <- maxent_auc(c(0.8, 0.9, 1.0), c(0.1, 0.2, 0.3))
result$auc # 1.0
#> [1] 1
