beats_random_baseline

mcda.beats_random_baseline(scores, polarity, baselines, metric_ids=None)

Count, per metric, how many tools score better than chance.

A tool beats chance on a metric when its score is strictly past the declared baseline in the metric’s favourable direction: above the baseline for a higher_is_better metric, below it for lower_is_better. A target_value metric has no chance level, so it is skipped even if a baseline is declared. Metrics without a baseline are skipped.
