flowmachine.features.location.unique_subscriber_counts

Class UniqueSubscriberCounts

UniqueSubscriberCounts(start, stop, spatial_unit: Union[flowmachine.core.spatial_unit.CellSpatialUnit, flowmachine.core.spatial_unit.GeomSpatialUnit] = CellSpatialUnit(), hours='all', table='all')
Source: flowmachine/features/location/unique_subscriber_counts.py

Class that defines counts of unique subscribers for each location. Each location for the given spatial unit is accompanied by the count of unique subscribers.

Attributes

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[flowmachine.core.spatial_unit.CellSpatialUnit, flowmachine.core.spatial_unit.GeomSpatialUnit], default CellSpatialUnit()

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

  • hours: tuple of ints, default 'all'

    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 pull together all of the tables specified as flowmachine.yml under 'location_tables'

  • 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.

  • ignore_nulls: bool, default True

    ignores those values that are null. Sometime data appears for which the cell is null. If set to true this will ignore those lines. If false these lines with null cells should still be present, although they contain no information on the subscribers location, they still tell us that the subscriber made a call at that time.

Examples

usc = UniqueSubscriberCounts('2016-01-01', '2016-01-04', spatial_unit=AdminSpatialUnit(level=3), hours=(5,17))
usc.head(4)
      name                  unique_subscriber_counts
0     Arghakhanchi          313
1     Baglung               415
2     Bajhang               285
