In MoNAn: Mobility Network Analysis

concentration_prop_AC

Description

Is there a bandwagon effect in mobility, i.e. do mobile individuals move to locations that are the destination of many others from their origin? The functional form of this statistic assumes that individuals consider the proportions of individuals (coming from the same origin) going to a certain destination, instead of the total number. This specification uses the idea that each individual's contribution is a function of the proportion of individuals from its origin going on the same tie as him/her. The function is defined as an increasing function with decreasing positive gradient, which means that the benefits of having additional individuals on a tie decrease with more individuals. It's a similar logic to the previous AC statistics.

Usage

concentration_prop_AC(
  dep.var = 1,
  state,
  cache,
  i,
  j,
  edge,
  update,
  getTargetContribution = FALSE,
  alpha = 2
)

Value

Returns the change statistic or target statistic of the effect for internal use by the estimation algorithm.
