psABAY: psABAY

In remstats: Computes Statistics for Relational Event History Data

psABAY

Description

Specifies the statistic for a participation shift AB-AY.

Usage

psABAY(consider_type = "ignore")

Arguments

consider_type

character. Controls how event types are handled: "ignore" (default): aggregate over all event types (one statistic); "separate": compute C type-specific statistics, where the type-c statistic for a dyad reflects past type-c events on that actor pair ; "interact": compute C^2 statistics capturing past-event-type x dyad-type interactions (only meaningful with extend_riskset_by_type=TRUE in remify object). Also accepts FALSE (-> "ignore") and TRUE (-> "separate") for backward compatibility.

Details

One of Gibson's (2003) dyadic participation shifts. The AB-AY participation shift refers to a tendency for turn continuing. For directed events, the sender (A) in the current event is the same as the sender in the previous event (A), and the receiver (Y) is different from the previous receiver (B). In undirected events, one of the current actors (A) matches one of the actors in the previous events (A or B), while the other actor (Y) is different.

To identify these shifts, a statistic 'psABAY' is calculated for each pair of actors at a given timepoint (t). If the pair's interaction follows the AB-AY pattern, the statistic is set equal to one; otherwise, it's set to zero.

Additionally, the types of the AB and AY events can be taken into account. If 'consider_type' is 'TRUE', the type of the AB event and the type of the AY event must match for the shift to occur. If 'consider_type' is 'FALSE', the shift happens for every AY event, regardless of the event type.

Value

List with all information required by 'remstats::remstats()' to compute the statistic.
