dens_test: Run the McCracy test for manipulation of the forcing variable

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

Description

Calls the DCdensity test from package rdd on a rdd_object.

Usage

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

Arguments

rdd_object	object of class rdd_data
bin	Argument of the DCdensity function, the binwidth
bw	Argument of the DCdensity function, the bandwidth
plot	Whether to return a plot. Logical, default ot TRUE.
...	Further arguments passed to DCdensity.

Examples

data(house)
house_rdd <- rdd_data(y=house$y, x=house$x, cutpoint=0)
dens_test(house_rdd)
