)Arguments
- data
A
data.frameholding the outcome, running variable, treatment, and any covariates referenced by name.- outcome
Character; column name of the response variable in
data.- running
Character; column name of the running (forcing) variable in
data.- cutoff
Numeric scalar; the threshold on
running. Default0(the canonical normalisation).- donut
Numeric; symmetric window around the cutoff to drop in a donut-RDD robustness check (default
0).- bandwidth
Numeric; the local-polynomial bandwidth on each side of the cutoff.
NULLinvokes the data-driven CCT selector.- p
Integer; local-polynomial order (default 1 for local- linear). 2 picks up quadratic curvature for bias correction.
- kernel
One of
"triangular"(default),"epanechnikov","uniform", or"gaussian".- alpha
Significance level (default
0.05).
