View source: R/PerformanceMeasures.R
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. |
.ras |
Internal parameter, do not use in the workflow function. |
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.
