dens_test: McCrary Sorting Test

In rddtools: Toolbox for Regression Discontinuity Design ('RDD')

McCrary Sorting Test

Description

This calls the original DCdensity function which was in the package rdd by Drew Dimmery, which has been archived and is now internally stored in the Rddtools package.

Usage

dens_test(rdd_object, bin = NULL, bw = NULL, plot = TRUE, ...)

Arguments

rdd_object	object of class rdd_data
bin	the binwidth (defaults to 2*sd(runvar)*length(runvar)^(-.5))
bw	the bandwidth to use (by default uses bandwidth selection calculation from McCrary (2008))
plot	Whether to return a plot. Logical, default to TRUE.
...	Further arguments passed to the unexported DCdensity function.

Details

Run the McCracy test for manipulation of the forcing variable
