ecospat.meva.table: Model Evaluation For A Given Threshold Value

Description

Calculates values of a series of different evaluations metrics for a model and for a given threshold value

Usage

ecospat.meva.table(Pred, Sp.occ, th)

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.
