Multivariate spline regression and predicted values
Hello, I am trying to estimate a multivariate regression of Y on X with regression splines. Y is (nx1), and X is (nxd), with d>1. I assume the data is generated by some unknown regression function f(X), as in Y = f(X) + u, where u is some well-behaved regression error. I want to estimate f(X) via regression splines (tensor product splines). Then, I want to get the predicted values for some new

mulitple mixed regression with spline
Hi, I'm looking to implement a regression with mixed terms. I have 2 biological endpoints for a dataset of n=77, one linearly related and the other fits a spline. I want to combine these two terms in a linear regression for prediction, then apply the model to a test set. this works fine, good r2 and I've graphed the spline. m1<-lm(y~x1,data=train) m2<-smooth.spline(x2,y); (spl)

finding the best cubic spline fitting
Hi, I am trying to fit cubic spline to a data on mortality rate by age and year (1900-2008). The data is noisy and hence I would like to smooth using spline and also extrapolate beyond 2008. Data from 1900 to 1948 are very unreliable while data from 1948 to 2008 are reliable. I would like to have a higher weight for data between 1948 to 2008. I am not sure how to do this. When I smooth data from

piece wise application of functions
Dear all, After struggling for some time with *apply() and eva() without success, I decided to ask for help. I have 3 lists labeled with, each contains 3 different interpolation functions with identical names: > names(missgp0) [1] "spl.1mb" "spl.2mb" "spl.5mb" > > names(missgp1) [1] "spl.1mb" "spl.2mb" "spl.5mb" > >

Trying to re-install ZFS drivers
What should have been a routine upgrade to ZFS 0.6.4.1-1.el6.x86_64 somehow failed, and now I've lost access to a 2T raidz2 array. I've tried removing all zfs and related packages (spl*), then starting fresh. For reasons that have have nothing to do with this problem (I don't think), I'm still booted to kernel 2.6.32-431.29.2.el6.x86_64, and there are no other kernels installed.

Barplot2 using for loop, how to adjust margins?
Hi R-users, I inted to make multiple plots using for loop. The question is how can I adjust the left hand side margin of the plot according to the names.arg argument in barplot2. In every plot I have different annotations in the y axis and they vary in length. Now when I have fixed margins opar <- par(mar=c(3,15,0,2)... I get the same margins in all of the plots. That leaves lots of white

Help with error on function: Error in .... attempt to apply non-function
Dear R gurrus, I wrote this function http://scsys.co.uk:8002/33852?ln=on&store=on&submit=Format+it! for a small package I am preparing. Whenever I run the function I get the error Error in Mspline(i = i, x = x, degree = kk, t = t) : attempt to apply non- function Anyone could point me out what I am doing wrong? kubuntu 904 64 bit, R 2.9.2 Regards -- Corrado Topi Global Climate

plot(all.effects)
Dear r-helpers, plot(all.effects()) uses trellis for its output, and often produces several effect plots in a layout. Can anyone tell me how to set the arguments to plot.effect which default to row=1, col=1, nrow=1, ncol=1, more=FALSE so that I can plot multiple effect plots on one layout? I was hoping that a call like last <- rep(c(TRUE, FALSE), c(3, 1)) lay <-matrix(c(1:4,), 2, 2,

-vn doesn't list empty directories, -v does
I'm using rsync-2.5.7-2 on an updated Fedora Core 1 athlon system. The -vn option lists all files to be copied or deleted, including symlinks, but it does not appear to list empty directories to be copied, even tough it copies them. It does list empty directories to be deleted. The -v option does list and copy empty directories. -v should behave the same in both instances, and the desired

recursive root finding
Dear list, I've had this problem for a while and I'm looking for a more general and robust technique than I've been able to imagine myself. I need to find N (typically N= 3 to 5) zeros in a function that is not a polynomial in a specified interval. The code below illustrates this, by creating a noisy curve with three peaks of different position, magnitude, width and

[LLVMdev] Custom allocation orders
The target description .td files are allowed to change the default allocation order on a register class by overriding the allocation_order_begin() and allocation_order_end() methods on TargetRegisterClass. Previously, this was used all the time to filter out stack and frame pointers and other reserved registers. I was able to remove most of these custom allocation orders in the tree because the
