bw_ik12

<code>bw_ik12</code> 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().

Estimation of both single- and multiple-assignment Regression Discontinuity Designs
(RDDs). Provides both parametric (global) and non-parametric (local) estimation choices for
both sharp and fuzzy designs, along with power analysis and assumption checks.
Introductions to the underlying logic and analysis of RDDs are in
Thistlethwaite, D. L., Campbell, D. T. (1960) <doi:10.1037/h0044319> and
Lee, D. S., Lemieux, T. (2010) <doi:10.1257/jel.48.2.281>.
