Anybody knows how to generate the basis matrix for smoothing spline? And how about the smoother matrix? I tried to use the following code, but there exist replicated data in X, and the length of smooth.spline(X, S[,i])$y is smaller than X, and then there is error in the last step.
spl <- smooth.spline(X, Y) S <- diag(X) for (i in 1:N) S[i,] <- smooth.spline(X, S[,i])$y #smoother matrix S Someone help please! Thanks in advance. -- View this message in context: http://n4.nabble.com/Smoothing-Spline-Basis-Matrix-tp1573131p1573131.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
