# RDDENSITY
Density discontinuity testing (a.k.a. manipulation testing)
is commonly employed in regression discontinuity designs
and other program evaluation settings to detect perfect self-selection (manipulation)
around a cutoff where treatment/policy assignment changes.
This package implements manipulation testing procedures using
the local polynomial density estimators:
rddensity() to construct test statistics and p-values given a prespecified cutoff,
rdbwdensity() to perform data-driven bandwidth selection,
and rdplotdensity() to construct density plots.
