flowmachine.features.subscriber.contact_balance

Source: flowmachine/features/subscriber/contact_balance.py

The total number of events that a subscriber interacts with a counterpart, and the proportion of events that a given contact participates out of the subscriber's total event count.

Class ContactBalance

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

This class calculates the total number of events that a subscriber interacts with a counterpart, and the proportion of events that a given contact participates out of the subscriber's total event count. This can be used to calculate a subscriber's contact network graph and the respective weighted edges for each contact.

Attributes

Parameters

  • start, stop: str

    iso-format start and stop datetimes

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

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

  • tables: str, default 'all'

  • exclude_self_calls: bool, default True

    Set to false to include calls a subscriber made to themself

  • 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

    Event direction to include in computation. This can be outgoing ('out'), incoming ('in'), or both ('both').

Methods

counterparts_subset

counterparts_subset(self, include_subscribers=False)
Source: flowmachine/features/subscriber/contact_balance.py

Returns the subset of counterparts. In some cases, we are interested in obtaining information about the subset of subscribers contacts. This method also allows one to get the subset of counterparts together with subscribers by turning the include_subscribers flag to True.

Parameters
  • include_subscribers: bool, default True

    Wether to include the list of subscribers in the subset as well.

cache

cache
Source: flowmachine/core/query.py

Returns
  • bool

    True is caching is switched on.

column_names

column_names
Source: flowmachine/features/subscriber/contact_balance.py

Returns the column names.

Returns
  • typing.List[str]

    List of the column names of this query.

column_names_as_string_list

column_names_as_string_list
Source: flowmachine/core/query.py

Get the column names as a comma separated list

Returns
  • str

    Comma separated list of column names

dependencies

dependencies
Source: flowmachine/core/query.py

Returns
  • set

    The set of queries which this one is directly dependent on.

fully_qualified_table_name

fully_qualified_table_name
Source: flowmachine/core/query.py

Returns a unique fully qualified name for the query to be stored as under the cache schema, based on a hash of the parameters, class, and subqueries.

Returns
  • str

    String form of the table's fqn

index_cols

index_cols
Source: flowmachine/core/query.py

A list of columns to use as indexes when storing this query.

Returns
  • ixen: list

    By default, returns the location columns if they are present and self.spatial_unit is defined, and the subscriber column.

Examples
daily_location("2016-01-01").index_cols
[['name'], '"subscriber"']

is_stored

is_stored
Source: flowmachine/core/query.py

Returns

Returns
  • str

    query_id hash string

query_state

query_state
Source: flowmachine/core/query.py

Return the current query state.

Returns
  • QueryState

    The current query state

query_state_str

query_state_str
Source: flowmachine/core/query.py

Return the current query state as a string

Returns
  • str

    The current query state. The possible values are the ones defined in flowmachine.core.query_state.QueryState.

table_name
