TrainTestFeatureDrift.add_condition_drift_score_not_greater_than(max_allowed_psi_score: float = 0.2, max_allowed_earth_movers_score: float = 0.1, number_of_top_features_to_consider: int = 5)[source]#

Add condition - require drift score to not be more than a certain threshold.

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

Parameters
max_allowed_psi_score: float , default: 0.2

the max threshold for the PSI score

max_allowed_earth_movers_score: float , default: 0.1

the max threshold for the Earth Mover’s Distance score

number_of_top_features_to_consider: int , default: 5

the number of top features for which exceed the threshold will fail the condition.

Returns
——-
ConditionResult

False if any column has passed the max threshold, True otherwise
