flowmachine.features.subscriber.pareto_interactions

Source: flowmachine/features/subscriber/pareto_interactions.py

This class calculates the Pareto proportion for a subscriber's interactions - that fraction of their contacts who account for 80% of their interactions.

Class ParetoInteractions

ParetoInteractions(start, stop, proportion=0.8, *, direction: Union[str, flowmachine.features.utilities.direction_enum.Direction] = <Direction.BOTH: 'both'>, tables='all', subscriber_identifier='msisdn', hours='all', exclude_self_calls=False, subscriber_subset=None)
Source: flowmachine/features/subscriber/pareto_interactions.py

Calculates the proportion of a subscriber's contacts who account for some proportion of their interactions, ala the Pareto Principle. Returns a two columns, a subscriber, pareto - the proportion of that subscribers contacts who account for the requested proportion (0.8, by default) of their interactions in this time period.

Attributes

Parameters

  • start, stop: str

    iso-format start and stop datetimes

  • hours: tuple of float, default 'all'

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

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

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

  • exclude_self_calls: bool, default True

    Set to false to include calls a subscriber made to themself

  • table: str, default 'all'

  • 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.

  • proportion: float

    proportion to track below
