Arguments
Pred
A vector of predicted probabilities
Sp.occ
A vector of binary observations of the species occurrence
th
Threshold used to cut the probability to binary values
Value
A contingency table of observations and predicted probabilities of presence values, and a list of evaluation metrics for the selected threshold.
