PerformanceMeasures: Output module: PerformanceMeasures
In zoonproject/modules: Species Distribution Modelling Code Modules for the ZOON Package

Calculate a suite of performance metrics on either crossvalidation, external validation data or (at your own risk) in-sample validation.

1	PerformanceMeasures(.model, .ras, threshold = NULL, print = TRUE)

`.model`	Internal parameter, do not use in the workflow function. `.model` is list of a data frame (`data`) and a model object (`model`). `.model` is passed automatically in workflow, combining data from the model module(s) and process module(s), to the output module(s) and should not be passed by the user.
`.ras`	Internal parameter, do not use in the workflow function. `.ras` is a raster layer, brick or stack object. `.ras` is passed automatically in workflow from the covariate module(s) to the output module(s) and should not be passed by the user.
`threshold`	A chosen threshold value for measures that need 0/1 predictions If NULL, the proportion of occurrences in the occurrence data is used.
`print`	If true then the data are returned to console as well as outputted

This model prints to console a number of metrics of the model fitted:

auc - (see ?SDMTools::auc) The Area Under the Curve of the Receiver operating characteristic using a Mann-Whitney U statistic
kappa - (see ?kappa) An estimate of the 2-norm condition number of a matrix or of the R matrix of a QR decomposition, perhaps of a linear fit. The 2-norm condition number can be shown to be the ratio of the largest to the smallest non-zero singular value of the matrix.
omissions - (see ?SDMTools::omission) The ommission rate as a proportion of true occurrences misidentified given the defined threshold value.
sensitivity - (see ?SDMTools::sensitivity) The proportion of actual presences predicted given the defined threshold value.
specificity - (see ?SDMTools::specificity) The proportion of actual absences predicted given the defined threshold value.
proportionCorrect - (see ?SDMTools::prop.correct) The proportion of the presence and absence records correctly identified given the defined threshold value.
