Specifies the statistic for a pshift AB-AB effect.
Arguments
- consider_type
logical, indicates whether to consider the event type in determining which dyads create a pshift (TRUE, default) or not (FALSE).
Details
Refers to the tendency for the same dyads to keep interacting. For directed events, the next sender and receiver are equal to the previous sender and receiver. For undirected events, the next actor pair is equal to the current actor pair. For each timepoint t, the psABAB statistic is equal to one for the dyads that will create the participation shift if they would occur in the edgelist at time t and equal to zero for the dyads that will not create this participation shift. If consider_type is set to TRUE, the type of the two subsequent AB events have to be equal. If it is set to FALSE, the participation shift is set to one for every AB event, regardless of the event type. If multiple events in the edgelist occur at the same time point, the order of these events determines whether the p-shift is observed.
Examples
reh_tie <- remify::remify(history, model = "tie", directed = FALSE)
effects <- ~ psABAB()
remstats(tie_effects = effects, reh = reh_tie)
