Imbens-Kalyanaraman 2012 Optimal Bandwidth Calculation
Description
bw_ik12 calculates the Imbens-Kalyanaraman (2012) optimal bandwidth
for local linear regression in regression discontinuity designs.
It is based on a function in the "rddtools" package.
This is an internal function and is typically not directly invoked by the user.
It can be accessed using the triple colon, as in rddapp:::bw_ik12().
Usage
bw_ik12(X, Y, cutpoint = NULL, verbose = FALSE, kernel = "triangular")
Arguments
X
A numeric vector containing the running variable.
Y
A numeric vector containing the outcome variable.
cutpoint
A numeric value containing the cutpoint at which assignment to the treatment is determined. The default is 0.
verbose
A logical value indicating whether to print more information to the terminal.
The default is FALSE.
kernel
A string indicating which kernel to use. Options are "triangular"
(default and recommended), "rectangular", "epanechnikov", "quartic",
"triweight", "tricube", and "cosine".
Value
ik_bw12 returns a numeric value specifying the optimal bandwidth.
