Description
Fit a principal curve which describes a smooth curve that passes through the middle
of the data x in an orthogonal sense. This curve is a non-parametric generalization
of a linear principal component. If a closed curve is fit (using smoother = "periodic_lowess")
then the starting curve defaults to a circle, and each fit is followed by a bias correction
suggested by Jeff Banfield.
