mgcv: increasing basis dimension
hi Using a ts or tprs basis, I expected gcv to decrease when increasing the basis dimension, as I thought this would minimise gcv over a larger subspace. But gcv increased. Here's an example. thanks for any comments. greg #simulate some data set.seed(0) x1<-runif(500) x2<-rnorm(500) x3<-rpois(500,3) d<-runi...

A question on orthogonal basis vectors
Hey, R-listers, I have a question about determining the orthogonal basis vectors. In the d-dimensinonal space, if I already know the first r orthogonal basis vectors, should I be able to determine the remaining d-r orthognal basis vectors automatically? Or the answer is not unique? Thanks for your attention. Fred

1st derivative {mgcv} gam smooth
Dear R-hep, I'm trying to get the first derivative of a smooth from a gam model like: model<-gam(y~s(x,bs="cr", k=5)+z) and need the derivative: ds(x)/dx. Since coef(model) give me all the parameters, including the parameters of the basis, I just need the 1st derivative of the basis s(x).1, s(x).2, s(x).3, s(x).4. If the basis were generated with the function spline.des() from the spline library I would be able to get the derivative of the basis and would be pretty much done. (spline.des() has the option of computing 1st derivative...

How to choose a proper smoothing spline in GAM of mgcv package?
Hi, there, I have 5 datasets. I would like to choose a basis spline with same knots in GAM function in order to obtain same basis function for 5 datasets. Moreover, the basis spline is used to for an interaction of two covarites. I used "cr" in one covariate, but it can only smooth w.r.t 1 covariate. Can anyone give me some suggestion about how t...

how to use the basis matrix of "ns" in R? really confused by multi-dim spline filtering?
...hey don't provide examples in R or Splus at all. Specifically, I don't know how to provide data "x" to the "ns" function in R, and I don't understand what should be the output matrix, and how to use the output matrix to "filter" data? Books mention about basis matrix, design matrix, model matrix, data matrix, etc. I got lost. I presume the output of the "ns" function in R is "basis matrix", but then how do I use it? How to form tensor-product? I don't understand it at all. Please help me! Thank you very much! [[alternative...

[LLVMdev] changing passes and changing subtargets on a per function basis
I'm implementing this capability to allow switching between mips32 and mips16 code generation on a per function basis (should be useful for arm to thumb switching too). The problem is that while various things are done on a per function basis, there are two passes registered on a per module basis (target lowering and instruction selection). With the new attribute scheme, we can wake up to reset target or su...

Inquiry:How to compare two files but not in line-by-line basis?
Dear All Can you please do me favor and let me know how can I compare two files but not in line-by-line basis on my CentOS server ? I mean say row#1 in file1 has the same data as say row#5 in file2 , but the comm compares them in line-by-line basis that is not intended . It seems that the diff cannot do the job as well .

help: what are the basis functions in {mgcv}: gam?
I am writing my thesis with the function gam(), with the package {mgcv}. My command is: gam(y~s(x1,bs="cr")+s(x2, bs="cr")). I need help to know what are the default basis funcitons for gam.

natural splines
Apologies if this is this too obscure for R-help. In package splines, ns(x,,knots,intercept=TRUE) produces an n by K+2 matrix N, the values of K+2 basis functions for the natural splines with K (internal) knots, evaluated at x. It does this by first generating an n by K+4 matrix B of unconstrained splines, then postmultiplying B by H, a K+4 by K+2 representation of the nullspace of C (2 by K+4), which contains the 2nd derivatives of the unconstra...
