flowmachine.features.location.total_events

Source: flowmachine/features/location/total_events.py

Calculates the number of events at a location during a specified time period.

Class TotalLocationEvents

TotalLocationEvents(start: str, stop: str, *, table: Union[NoneType, List[str]] = None, spatial_unit: Union[flowmachine.core.spatial_unit.CellSpatialUnit, flowmachine.core.spatial_unit.GeomSpatialUnit] = CellSpatialUnit(), interval: str = 'hour', direction: Union[str, flowmachine.features.utilities.direction_enum.Direction] = <Direction.BOTH: 'both'>, hours: Union[Tuple[int, int], NoneType] = None, subscriber_subset=None, subscriber_identifier='msisdn')

Source: flowmachine/features/location/total_events.py

Calculates the total number of events on an hourly basis per location (such as a tower or admin region), and per interaction type.

Parameters

• start: str

  ISO format date string to at which to start the analysis

• stop: str

  As above for the end of the analysis

• table: typing.Union[NoneType, typing.List[str]], default None

  Specifies a table of cdr data on which to base the analysis. Table must exist in events schema. If 'all' then we use all tables specified in flowmachine.yml.

• 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.

• interval: str, default hour

  Records activity on an hourly, daily, or by minute level.

• direction: typing.Union[str, flowmachine.features.utilities.direction_enum.Direction], default both

  Look only at incoming or outgoing events. Can be either 'out', 'in' or 'both'.
