A Smooth Monotone Warping Function

A Smooth Monotone Warping Function

DESCRIPTION:

This function does nearly the same thing that function smooth.monotone does, but in this case the constants b0 and b1 are determined so that the initial value of the warping function is the same as the initial argument value, and the final warping function value is the same as the final argument values. This function is mainly used in function landmarkreg to ensure that the warping function is monotone.

USAGE:

warpsmth(x, y, wt=rep(1, nobs), Wfd, Lfd=1, lambda=0, conv=0.0001, iterlim=20, active=rep(T, nbasis), dbglev=0)

ARGUMENTS:

See the help file for smooth.monotone.

VALUE:

See the help file for smooth.monotone.
