pm4py.filtering.filter_variants_by_coverage_percentage

pm4py.filtering.filter_variants_by_coverage_percentage(log: EventLog | DataFrame, min_coverage_percentage: float, activity_key: str = 'concept:name', timestamp_key: str = 'time:timestamp', case_id_key: str = 'case:concept:name') → EventLog | DataFrame

Filters the variants of the log by a coverage percentage (e.g., if min_coverage_percentage=0.4, and we have a log with 1000 cases, of which 500 of the variant 1, 400 of the variant 2, and 100 of the variant 3, the filter keeps only the traces of variant 1 and variant 2).

Parameters:

• log – event log / Pandas dataframe

• min_coverage_percentage (float) – minimum allowed percentage of coverage

• activity_key (str) – attribute to be used for the activity

• timestamp_key (str) – attribute to be used for the timestamp

• case_id_key (str) – attribute to be used as case identifier

Return type:

Union[EventLog, pd.DataFrame]
