redist.plot.penalty: (Deprecated) Visualize Group Power Penalty

In redist: Simulation Methods for Legislative Redistricting

(Deprecated) Visualize Group Power Penalty

Description

Plots the shape of the add_constr_grp_pow() 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.

Details

This function allows you to plot the un-exponentiated penalty implemented as add_constr_grp_pow(). 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.
