otp: otp

In remstats: Computes Statistics for Relational Event History Data

otp

Description

Specifies the statistic for an outgoing two-path effect.

Usage

otp(unique = FALSE, scaling = c("none", "std"), consider_type = TRUE)

Arguments

unique	A logical value indicating whether to sum the minimum of events with third actors (FALSE, default) or the number of third actors that create a new, unique two-path (TRUE). See details for more information.
scaling	The method for scaling the triad statistic. The default value is "none", which means the statistic is not scaled. Alternatively, you can set it to "std" to request standardization of the raw counts per time point.
consider_type	A logical value indicating whether to count the two-paths separately for each event type (TRUE, default) or sum across different event types (FALSE).

Details

The outgoing two-path effect describes the propensity of dyads to interact based on the number of past outgoing two-paths between them. By default, the statistic at timepoint t for the dyad (i,j) is computed as the sum of the minimum occurrences of past (i,h) and (h,j) events across all actors h.

When the unique parameter is set to TRUE, a different approach is taken. In this case, the statistic counts the number of actors h that contribute to the creation of a new, distinct two-path between actors i and j.

Additionally, it is possible to specify a scaling method using the scaling parameter.

Please note that the outgoing two-path effect, 'otp', is exclusively defined for directed events.

Value

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

reh_tie <- remify::remify(history, model = "tie")
effects <- ~ otp()

reh_actor <- remify::remify(history, model = "actor")
remstats(reh = reh_actor, receiver_effects = effects)
