redist (version 3.1.5)

redist.plot.penalty: Visualize VRA Penalty

Description

Plots the shape of the VRA Gibbs penalty.

Usage

redist.plot.penalty(
  tgt_min = 0.55,
  tgt_other = 0.25,
  strength_vra = 2500,
  pow_vra = 1.5,
  limits = TRUE
)

Arguments

tgt_min

double, defaults to 0.55. The minority target percent.

tgt_other

double, defaults to 0.25. The other group target percent.

strength_vra

double, strength of the VRA constraint.

pow_vra

double, exponent of the VRA constraint.

limits

Whether to limit y axis to 0,500. Default is TRUE for comparability across values.

Value

ggplot

Details

This function allows you to plot the un-exponentiated VRA Gibbs penalty implemented as `vra` within MCMC, Merge-Split, and SMC. The function takes two key inputs, `tgt_min` and `tgt_other` which center the minimum penalty spots. A higher y-value indicates a higher penalty and incentivizes moving towards a spot with a lower y-value. The x-axis indicates the group population proportion in a given district. The default indicates the default settings within redist_smc().
