flowmachine.features.subscriber.most_frequent_location

Source: flowmachine/features/subscriber/most_frequent_location.py

Computes the location in which an subscriber has been the most frequently.

Class MostFrequentLocation

MostFrequentLocation(start, stop, spatial_unit: Union[flowmachine.core.spatial_unit.CellSpatialUnit, flowmachine.core.spatial_unit.GeomSpatialUnit, NoneType] = None, hours: Optional[Tuple[int, int]] = None, table='all', subscriber_identifier='msisdn', *, ignore_nulls=True, subscriber_subset=None)

Source: flowmachine/features/subscriber/most_frequent_location.py

Class representing the subscribers most frequent location within a certain time frame

Attributes

• cache

• column_names

• column_names_as_string_list

• dependencies

• fully_qualified_table_name

• index_cols

• is_stored

• query_id

• query_state

• query_state_str

• table_name

Parameters

• start: str

  iso format date range for the beginning of the time frame, e.g. 2016-01-01 or 2016-01-01 14:03:01

• stop: str

  As above

• spatial_unit: typing.Union, default None

  Spatial unit to which subscriber locations will be mapped. See the docstring of make_spatial_unit for more information.

• hours: typing.Optional, default None

  Subset the result within certain hours, e.g. (4,17) This will subset the query only with these hours, but across all specified days. Or set to 'all' to include all hours.

• table: str, default 'all'

  schema qualified name of the table which the analysis is based upon. If 'all' it will use all tables that contain location data.

• subscriber_identifier: {'msisdn', 'imei'}, default 'msisdn'

  Either msisdn, or imei, the column that identifies the subscriber.

• subscriber_subset: flowmachine.core.Table, flowmachine.core.Query, list, str, default None

  If provided, string or list of string which are msisdn or imeis to limit results to; or, a query or table which has a column with a name matching subscriber_identifier (typically, msisdn), to limit results to.

Note

• A date without a hours and mins will be interpreted as midnight of that day, so to get data within a single day pass (e.g.) '2016-01-01', '2016-01-02'. * Use 24 hr format!
