A table containing the thresholds used to assign habitat as Category 2 (ie in use) based on probability of use. Developed by Rempel and Hornseth using Youden's J and a false negative cost of 5.
threshTableA data frame with 48 rows and 6 variables:
Range: the caribou range name
Season: season, one of Spring, Summer, Fall, Winter
Sensitivity: the proportion of presences correctly predicted as presence
Specificity: the proportion of absences correctly predicted as absence
Threshold: the value for the lowest probability of use that is considered a predicted presence
AUC: the area under the resource operating characteristic (ROC) curve; it ranges from 0-1 and indicates the overall success of the model for predicting both presence and absence
