plotpi: Plots of piFunction

In PropScrRand: Propensity Score Methods for Assigning Treatment in Randomized Trials

Plots of piFunction

Description

Can be used to investigate the strength of balance forced by various values of the tuning parameter k.

Usage

plotpi(k, global = 0.5)
addpi(k, global = 0.5, ...)

Arguments

k	Balancing parameter.
global	Global target for proportion of units treated.
...	Parameters in addpi passed to lines function.

Details

The function plotpi creates a plot of treatment probability against fitted propensity score for values of k and global. The function addpi adds a curve for a new combination of k and global to an existing plot.

Examples

plotpi(k=3, global=0.5)
addpi(k=5/3, lty=2, col='red')
plotpi(k=1/3, global=2/3)
