'drifter' calculates distances between variable\ndistributions or variable relations and identifies both types\nof drift. Key functions are: calculate_covariate_drift() checks\ndistance between corresponding variables in two datasets,\ncalculate_residuals_drift() checks distance between residual\ndistributions for two models, calculate_model_drift() checks\ndistance between partial dependency profiles for two models,\ncheck_drift() executes all checks against drift.
