indegreeReceiver: indegreeReceiver

Description

Specifies the statistic for an `indegreeReceiver` effect in the tie-oriented model or the receiver choice step of the actor-oriented model.

Usage

indegreeReceiver(scaling = c("none", "prop", "std"), consider_type = TRUE)

Value

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

Arguments

scaling: the method for scaling the degree statistic. Default is to not scale the statistic (scaling = "none"). Alternatively, scaling of the raw degree counts by the number of past events at time t can be requested with 'prop' or standardization of the raw degree counts per time point can be requested with 'std'.
consider_type: logical, indicates whether to count the degrees separately for each event type (TRUE, default) or sum degrees across different event types (FALSE).

Details

An indegree of the receiver effect refers to the tendency for actors to receive events if they have received more past events. The statistic at timepoint t for dyad (i,j) (tie-oriented model) or receiver j (actor-oriented model) is equal to the number of events received by actor j before timepoint t. Note that the 'indegreeReceiver' effect is only defined for directed events.

Optionally, a scaling method can be set with scaling. By scaling the degree count by the total number of past events, the statistic refers to the fraction of past events that were received by actor j. At the first time point, when no events did previously occur, it is assumed that every actor is equally likely to receive a message and the statistic is set equal to 1/ n, where n refers to the number of actors.

Examples

Run this code

reh_tie <- remify::remify(history, model = "tie")
effects <- ~ indegreeReceiver()
remstats(reh = reh_tie, tie_effects = effects)

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