J_admissible: Admissible Rank Transformations of Eichner & Stute (2013)
Description
This is just a wrapper for the functions J1, J2,
and \(u -> \sqrt 3 * (2u - 1)\) which implement the admissible
transformations for the three cases for \(c\). For mathematical
details see eq. (15.16) and (15.17) in Eichner (2017) and/or Eichner &
Stute (2013).
Usage
J_admissible(u, cc = sqrt(5))
Arguments
u
Numeric vector.
cc
Numeric constant, defaults to \(\sqrt 5\).
Value
Vector of same length and mode as u.
Details
Basically, for cc in \([\sqrt(5/3), \sqrt 5]\):
J_admissible(u, cc) = J1(u, cc) if cc \(< \sqrt 3\),
J_admissible(u, cc) = J2(u, cc) if cc \(> \sqrt 3\),
and
J_admissible(u, cc) = sqrt(3) * (2*u - 1) if cc
\(= \sqrt 3\).
