Table 3.

Results of the Wilcoxon signed-rank test for matched samples comparing the discrimination (AUC: Area Under the Curve) and classification (Sensitivity, Specificity, CCR or Correct Classification Rate, Und or Under Prediction Rate and Ove or Over Prediction Rate) performance of models based on expert knowledge and models based on species records, for the three groups of species: threatened (T), non-endangered and non-ubiquitous (NtNu), and ubiquitous (U) species separately. St. = Standardized Wilcoxon signed-rank statistic. Sig. = Significance. Negative values of the statistics mean that models based on species records had higher values than those based on expert knowledge
