Why would you want offsets in a regression?: just subtract them from the lhs. (R's lm has gained offsets by analogy with glm, but the S original did not have them). If you would be more comfortable working with them, it would be very easy to create a modified version that supports them. Also, have you heard of the 'curse of dimensionality'? Localization even to 4 dimensions is no longer really an appropriate term, and Euclidean distance will be the main determinant of 'local' and is quite arbitrary. > Thanks, > > Paul Louisell > 650-833-6254 > [EMAIL PROTECTED] > Research Associate (Statistician) > Modeling & Data Analytics > ARPC > > > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@stat.math.ethz.ch 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. > -- Brian D.
