err defines the error rate as the complement of
accuracy acc or lack of correspondence
of decisions to conditions.
errAn object of class numeric of length 1.
Definition:
err = (1 - acc)
When freq are not rounded (round = FALSE) then
err is currently not included in prob,
but shown in plots.
See err's complement of accuracy acc
for computation and
accu for current accuracy metrics
and several possible interpretations of accuracy.
acc provides overall accuracy;
comp_acc computes accuracy from probabilities;
accu lists current accuracy metrics;
comp_accu_prob computes exact accuracy metrics from probabilities;
comp_accu_freq computes accuracy metrics from frequencies;
comp_sens and comp_PPV compute related probabilities;
is_extreme_prob_set verifies extreme cases;
comp_complement computes a probability's complement;
is_complement verifies probability complements;
comp_prob computes current probability information;
prob contains current probability information;
is_prob verifies probabilities.
