"Earlyclobber" but for a subset of the inputs
Hi all,
I'm working on a target whose registers have equal-sized subregisters and
all of those subregisters can be named (or the other way round: registers
can be grouped into super registers).
So for instance we've got 16 registers W (as in wide) W0..W15 and 32
registers N (as in narrow) N0..N31. This way, W0 is made by grouping N0 and
N1, W1 is N2 and N3, W2 is N4 and N5, ..., W15 is

logistic regression: wls and unbalanced samples
Greetings from Rio de Janeiro, Brazil.
I am looking for advice / references on binary logistic regression
with weighted least squares (using lrm & weights), on the following
context:
1) unbalanced sample (n0=10000, n1=700);
2) sampling weights used to rebalance the sample (w0=1, w1=14.29); e
3) after modelling, adjust the intercept in order to reflect the
expected % of 1?s in the population

[LLVMdev] why functionattrs doesn't add dependency of AliasAnalysis
Hi, List,
As you may know, BCC of android makes use of LLVM's major components. Its
LTO actually selects some optimizations of LLVM.
I found it can not only use "-functionattrs". I must first use
-argpromotion first, or I end up this error:
Pass 'Deduce function attributes' is not initialized.
Verify if there is a pass dependency cycle.

qemu-xen qdisk performance
Hello,
I''ve recently setup a Linux Dom0 with a 3.0.17 kernel and Xen 4.1.2,
and since the 3.x series doesn''t have blktap support I''m using qdisk
to attach raw images. I''ve been playing with small images, something
like 1GB, and everything seemed fine, speed was not fantastic but it
was ok. Today I''ve set up a bigger machine, with a 20GB raw hdd and

[GSOC] "Project: Improve inter-procedural analyses and optimisations"
Hi all,
My name is Fahad Nayyar. I am an undergraduate student from India.
I am interested to participate in GSOC under the project “Improve
inter-procedural analyses and optimizations”.
I have been using LLVM for the past 8 months. I have written various
intra-procedural analysis in LLVM as FunctionPass for my course projects
and research projects. But I’ve not contributed to the LLVM

Using Predict and GLM
Dear R Help,
I read through the archives pretty extensively before sending this
email, as it seemed there were several threads on using predict with
GLM. However, while my issue is similar to previous posts (cannot
get it to predict using new data), none of the suggested fixes are
working.
The important bits of my code:

Hi all,
When I try to estimate the functional response of the Rogers type I

llvm combines "ADD frameindex, constant" to OR
Hi all,
I've been working on a backend of our architecture and noticed llvm performs
following combining although one of operands is FrameIndex.
Combining: t114: i64 = add FrameIndex:i64<0>, Constant:i64<56>
Creating new node: t121: i64 = or FrameIndex:i64<0>, Constant:i64<56>

regression for poisson distributed data
Hello all,
I would like to get parameter estimates for different models. For one of
them I give the code in example. I am estimating the parameters (i,j and
k) with the nls function, which sees the error distribution as normal, I
would however like to do the same as nls with the assumption that the
errors are poisson distributed.
Is there a way to do this with R? Are there packages designed

nls question
I'm using the nls library to fit peaks in spectra. The model
that I'm using is a quadratic background plus a Gaussian peak.
The peak is well described by the Gaussian and the background is
mostly linear with a bit of quadratic. My goal is an estimate of
the integral (and the uncertainty of the integral) of the peak
without the back ground.
The procedure that I'm using is as

Help using tapply with multiple variables
Dear list,
I have the function (as a simple example, which is actually part of a
larger function)
pres.test<-function(N0=N0, N1=N1)
{
dt<-5
r<-log(N1/N0)/dt
r
}
which calculates the annual growth rates in a population
Where N0 is the population classified into age intervals, say 5
years, at time=1995, and N1 is the population by 5 year age classes
at time=2000.

help a newbie with a loop
Hi,
I am new in R and stumbled on a problem my (more experienced) friends
can not help with with. Why isnt this code working?
The function is working, also with the loop and the graph appears,
only when I build another loop around it (for different values of p) ,
R stays in a loop?
Can't it take more then 2 loops in one program?
