TrainTestFeatureDrift.add_condition_drift_score_less_than#

TrainTestFeatureDrift.add_condition_drift_score_less_than(max_allowed_categorical_score: float = 0.2, max_allowed_numeric_score: float = 0.1, allowed_num_features_exceeding_threshold: int = 0)[source]#

Add condition - require drift score to be less than the threshold.

The industry standard for PSI limit is above 0.2. Cramer’s V does not have a common industry standard. Earth movers does not have a common industry standard.

Parameters
max_allowed_categorical_score: float , default: 0.2

The max threshold for the categorical variable drift score

max_allowed_numeric_score: float , default: 0.1

The max threshold for the numeric variable drift score

allowed_num_features_exceeding_threshold: int , default: 0

Determines the number of features with drift score above threshold needed to fail the condition.

Returns
ConditionResult

False if more than allowed_num_features_exceeding_threshold drift scores are above threshold, True otherwise
