AUC test
A greater number of optimal models selected by the EXP approach for fish
had a greater AUCTEST over other approaches, while for
the odonates the ORTEST approaches had greater number of
optimal models with greater AUCTEST followed by the EXP
approach (Figures 3g-h). Overall the AUCTEST values of
optimal models chosen by all five approaches were high (Figures 3g-h)
except for one fish species Schizothorax progastus which had an
AUCTEST value of .382 for the optimal models selected by
ORTEST_PER and AUCDIFF_PER approaches
(Figures 3g-h). There was also a high to very high statistically
significant positive correlation for the AUCTEST among
the optimal models chosen by all the approaches (Table S4) suggesting
all five selection approaches may select equally the optimal models with
good discriminatory power.
