Cox Regression : Spline Coefficient Interpretation?
Always reply to the list. I do not do private consulting.
(I have cc'ed this to the list).
I still think this belongs on stackexchange, not r-help. I think you need
to read up on the mathematics of spline bases.
Cheers,

Cox Regression : Spline Coefficient Interpretation?
Hi,
I'm using a Cox-Regression to estimate hazard rates on prepayments.
I'm using the "pspline" function to face non-linearity, but I have no clue
how to interpret the result.
Unfortunately I did not find enough information on the "pspline" function
wether in the survival package nor using google..
I got following output:

Why do I get different results for type III anova using the drop1 or Anova command?
Dear experts,
I just noticed that I get different results conducting type III anova
using drop1 or the Anova command from the car package. I suppose I made
a mistake and hope you can offer me some help. I have no idea where I
got wrong and would be very grateful for explaination as R is new
terrain for me.
If I run the commands in line, they produce the same results. But if I
run them in

help--Cox ph model
Dear r-users,
I want to use the Cox's ph model to analyze survival data set. How can I
extract the model coefs. and Wald test p-value or Score?
For example: I use the data set melanom in iSwR package.

simple line graphics, labels and legend
Dear users,
I think my questions are pretty simple, but I got lost in the hundreds
of par() and plot() arguments and plot functions, so I don't know in
which direction I should go.
Here is my sample dataset:
test <- structure(list(DIET = structure(c(1L, 1L, 1L, 1L, 1L, 3L, 3L,

Difference in ANOVA results - R vs. JMP/Minitab
Hi,
I ran a small data set from a factorial experiment through R, Minitab
and JMP... the result from R is significantly different from what
Minitab or JMP give... The data set is at the following link:

The first 5 columns are the factors and the next three are responses.

[LLVMdev] [RFC] AArch64: Should we disable GlobalMerge?
Hi all,
I've started looking at the GlobalMerge pass, enabled by default on
ARM and AArch64. I think we should reconsider that, at least for
AArch64.
As is, the pass just merges all globals together, in groups of 4KB
(AArch64, 128B on ARM).
At the time it was enabled, the general thinking was "it's almost
free, it doesn't affect performance much, we might as well use it".

[LLVMdev] 2.1 Pre-Release Available (testers needed)
LLVMers,
The 2.1 pre-release (version 1) is available for testing:
http://llvm.org/prereleases/2.1/version1/
I'm looking for members of the LLVM community to test the 2.1
release. There are 2 ways you can help:
1) Download llvm-2.1, llvm-test-2.1, and the appropriate llvm-gcc4.0
binary. Run "make check" and the full llvm-test suite (make
TEST=nightly report).
2) Download
