ecospat.max.kappa: Maximum Kappa

In ecospat: Spatial Ecology Miscellaneous Methods

Maximum Kappa

Description

Calculates values for Cohen's Kappa along different thresholds, considering this time 0.01 increments (i.e. 99 thresholds).

Usage

    ecospat.max.kappa(Pred, Sp.occ)

Arguments

Pred	A vector of predicted probabilities
Sp.occ	A vector of binary observations of the species occurrence

Value

Return values for Cohen's Kappa for 99 thresholds at 0.01 increments.
