Bert - when I hear "interpolate", I think of connecting the data points, like using something like divided differences or hermite interpolation, so I thought that's what you meant. Sorry for the misunderstanding. True that loess was designed to be robust, but when I said it is meant for normal-like errors, I was referring to loess with statistical procedures analagous to the classical regression setting, such as confidence intervals, anova, etc. (see "Locally Weighted Regression: An Approach to Regression Analysis by Local Fitting", 1988). ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
