pm4py.filtering.filter_log_relative_occurrence_event_attribute

pm4py.filtering.filter_log_relative_occurrence_event_attribute(log: EventLog | DataFrame, min_relative_stake: float, attribute_key: str = 'concept:name', level='cases', timestamp_key: str = 'time:timestamp', case_id_key: str = 'case:concept:name') → EventLog | DataFrame

Filters the event log keeping only the events having an attribute value which occurs: - in at least the specified (min_relative_stake) percentage of events, when level=”events” - in at least the specified (min_relative_stake) percentage of cases, when level=”cases”

Parameters:

• log – event log / Pandas dataframe

• min_relative_stake (float) – minimum percentage of cases (expressed as a number between 0 and 1) in which the attribute should occur.

• attribute_key (str) – the attribute to filter

• level (str) – the level of the filter (if level=”events”, then events / if level=”cases”, then cases)

• 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]
