Plots the shape of the [add_constr_grp_pow()] penalty.

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.
