Class LocationIntroversion

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

Source: flowmachine/features/location/location_introversion.py

Calculates the proportions of events that take place within a location in which all involved parties are located in the same location (introversion), and those which are between parties in different locations (extroversion).

Attributes

• cache

• column_names

• column_names_as_string_list

• dependencies

• fully_qualified_table_name

• index_cols

• is_stored

• query_id

• query_state

• query_state_str

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: str, default all

  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.

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

  Determines if query should filter only outgoing events ('out'), incoming events ('in'), or both ('both').

Examples

LocationIntroversion("2016-01-01", "2016-01-07").head()
      location_id  introversion  extroversion
0    AUQZGMW3      0.050000      0.950000
1    ns6vzdkC      0.049180      0.950820
2    llTlNC7E      0.046122      0.953878
3    WET2L101      0.045549      0.954451
4    eAwMUT94      0.045175      0.954825

Note

Equation 3 of the original paper states introversion as the ratio of introverted to extroverted events but indicates that this will return values in the range [0, 1]. However, the preceding text indicate that introversion is the proportion of events which are introverted. We follow the latter here.

Methods

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
