z_score_boost_errors

z_score_boost_errors(prob: AlignmentProblem, threshold=4, positive_only=True)

Boosted z-score errors

Parameters:

• prob – Alignment problem

• threshold – boosting threshold

Returns: boosted z-score errors

This function first computes normal z-scores. It then uses threshold to identify outliers. If positive_only=True (the default), only positive z-scores are considered as outliers. The identified outliers are removed when computing the means and standard deviations and the z-scores are recomputed based on the outlier-corrected mean and standard deviation.
