[R] information about Loess

[Greg Snow]

The loess.demo function in the TeachingDemos package may help you
understand what is going on.  Note that the default for loess in R does
an additional spline smooth/interpolation which may explain small
differences from other tools.

Hello,

I'm currently using a tool that provides a Loess fitting, but I
obtained results that are slightly different from those provided by R
implementation of the Loess. That's why I would like to know if you
could give me a source (bibliography or web) that explains in a clear
way each step of the algorithm, with the possible options to choose,
etc.. in order for me to understand those differences.

Thank you,

Naomi Berdugo.
