Suite for detecting integrity issues within a single dataset.

List of Checks:

Parameters

columnsUnion[Hashable, List[Hashable]] , default: None: The columns to be checked. If None, all columns will be checked except the ones in ignore_columns.
ignore_columnsUnion[Hashable, List[Hashable]] , default: None: The columns to be ignored. If None, no columns will be ignored.
n_top_columnsint , optional: number of columns to show ordered by feature importance (date, index, label are first) (check dependent)
n_samplesint , default: 1_000_000: number of samples to use for checks that sample data. If none, using the default n_samples per check.
random_stateint, default: 42: random seed for all checks.
n_to_showint , default: 5: number of top results to show (check dependent)
**kwargsdict: additional arguments to pass to the checks.

Returns

Suite: A suite for detecting integrity issues within a single dataset.
