Specifies the statistic for a recency send of sender effect in the effects argument of tomstats or the sender_effects argument of aomstats.

Usage

recencySendSender(consider_type = TRUE)

Arguments

consider_type

logical, indicates whether to compute the recency separately for each event type (TRUE, default) or regardless of event types (FALSE).

Value

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

Details

The recencySendSender effect refers to a recency statistic similar to what is described in Vu et al. (2017) and Mulder and Leenders (2019). For each timepoint t, for directed dyad (i,j) the statistic is equal to 1/(the time that has past since sender i was last active as sender + 1). Note that the 'recencySendSender' effect is only defined for directed events.

Examples

effects <- ~ recencySendSender()
reh_tie <- remify::remify(history, model = "tie")
remstats(tie_effects = effects, reh = reh_tie)
#> Relational Event Network Statistics
#> > Model: tie-oriented
#> > Computation method: per time point
#> > Dimensions: 115 time points x 90 dyads x 2 statistics
#> > Statistics:
#> 	 >> 1: baseline
#> 	 >> 2: recencySendSender

reh_actor <- remify::remify(history, model = "actor")
remstats(sender_effects = effects, reh = reh_actor)
#> Relational Event Network Statistics
#> > Model: actor-oriented
#> > Computation method: per time point
#> > Sender model:
#> 	 >> Dimensions: 115 time points x 10 actors x 2 statistics
#> 	 >> Statistics:
#> 	 	 >>> 1: baseline
#> 	 	 >>> 2: recencySendSender
