st: RE: RE: Loess confidence bands
John Fox gives a strategy for calculating what he calls a "pointwise 95% confidence envelope." Reference follows:
John Fox (2000). Nonparametric Simple Regression: Smooothing Scatterplots. Quantitative Applications in the Social Sciences, 07-130. Sage Publications.

Subject: st: RE: Loess confidence bands
I don't know about -loess-. That would presumably
a privately available user-written analogue of -lowess-.
Be that as it may, -lowess- doesn't support confidence
bands. Is anyone aware that they are even defined in the literature?
