flowmachine.features.subscriber.per_location_event_stats

Class PerLocationEventStats

PerLocationEventStats(start, stop, statistic='avg', *, spatial_unit: Union[flowmachine.core.spatial_unit.CellSpatialUnit, flowmachine.core.spatial_unit.GeomSpatialUnit] = CellSpatialUnit(), hours='all', tables='all', subscriber_identifier='msisdn', direction: Union[str, flowmachine.features.utilities.direction_enum.Direction] = <Direction.BOTH: 'both'>, subscriber_subset=None)
Source: flowmachine/features/subscriber/per_location_event_stats.py

This class returns the statistics of event count per location per subscriber within the period, optionally limited to only incoming or outgoing events. For instance, it calculates the average number of events per cell per subscriber.

Attributes

Parameters

  • start, stop: str

    iso-format start and stop datetimes

  • statistic: {'count', 'sum', 'avg', 'max', 'min', 'median', 'mode', 'stddev', 'variance'}, default 'avg'

    Defaults to avg, aggregation statistic over the durations.

  • hours: 2-tuple of floats, default 'all'

    Restrict the analysis to only a certain set of hours within each day.

  • 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.

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

    Whether to consider calls made, received, or both. Defaults to 'both'.

  • tables: list of strings, str, default 'all'

    Can be a string of a single table (with the schema) or a list of these. The keyword all is to select all subscriber tables

  • 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.
