Generalized logit transform

Description

maps a bounded parameter x onto the real line according to y=log((x-xl)/(xu-x))), with xl < x < xu. If this constraint is violated, an error occurs. x may be vector

Usage

ftrf(x, xl, xu)

x	a numeric vector
xl	a numeric vector of same length as x with x > xl
xu	a numeric vector of same length as x with x < xu
