Returns:

pandas.Series: A vector of bounds on group-level losses

default_objective()[source]#: Return a default objective.

gamma(predictor)[source]#: Calculate the degree to which constraints are currently violated by the predictor.

load_data(X, y, *, sensitive_features)[source]#: Load data into the moment object.

project_lambda(lambda_vec)[source]#: Return the lambda values.

signed_weights(lambda_vec=None)[source]#: Return the signed weights.

property total_samples#: Return the number of samples in the data.
