One rather theoretical question about fitting algorithm
Hi,
What I'm trying to achieve is very fast algorithm for fitting logistic
regression model. I have to estimate regression coeficients using
about 10k observations. Once I have coefficients estimated, new 100
rows of data becomes available.... Now I need to reestimate
coeficients using 100 newly arrived observations and removing 100
oldest observations.
So, my question is would it be

Coeficients estimation in a repeated measures linear model
Dear Users,
I am trying to understand the inner workings of a repeated measures linear
model. Take for example a situation with 6 individuals sampled twice for
two conditions (control and treated).
set.seed(12)
ctrl <- rnorm(n = 6, mean = 2)
ttd <- rnorm(n = 6, mean = 10)
dat <- data.frame(vals = c(ctrl, ttd),
group = c(rep("ctrl", 6), rep("ttd",

How to revert a change properly
The "Revert [tag] message" is the default message generated by the 'git revert' command. Of course you would have to be using a git clone of LLVM instead of an SVN checkout in order to run 'git revert'. This command is the equivalent of 'svn merge –r' run from the top-level directory. I believe svn commands will operate only on the directories below the current

plotting lm coeficients with their means
I am trying to write a function that will run a linear
model and plot the regression coeficients with their
corresponding means. I am having two problems. I can
get the plot with the function below, but I am having
trouble labeling the points.
function(y,x1,x2,x3,x4){
outlm<-lm(y~x1+x2+x3+x4)
imp<-as.data.frame(outlm$coef[-1])
meanvec<-c(mean(x1),mean(x2),mean(x3),mean(x4))

R-help Digest, Vol 35, Issue 24
Dear Prof Ripley,
First of all, unless you are an english professor, then I do not think you have
any business policing language. I'm still very much a student, both in R, and
regarding signal analysis. My competence on the subject as compared too your
own level of expertise, or my spelling for that matter, may be a contension for
you, but it would have been better had you kept that opinion

How to calculate Hightest Posterior Density (HPD) of coeficients in a simple regression (lm) in R?
Hi!
I am trying to calculate HPD for the coeficients of regression models
fitted with lm or lmrob in R, pretty much in the same way that can be
accomplished by the association of mcmcsamp and HPDinterval functions for
multilevel models fitted with lmer. Can anyone point me in the right
direction on which packages/how to implement this?
Thanks for your time!

What's "register pressure set"
Hi Xing,
The register pressure sets are basically concepts that tells you how may variables can live in register at the same time.
This information is available for two different level of abstraction: per register class and per register unit. The register unit is the basic entity we use to represent a register.
Tablegen generates all of that for you, so you do not need to worry about them.

str() to extract components
Hi,
I have been dabbling with str() to extract values from outputs such as
lmer etc and have found it very helpful sometimes.
but only seem to manage to extract the values when the output is one
simple table, any more complicated and I'm stumped :-(
take this example of the extracted coeficients from a lmer analysis...
using str(coef(lmer(resp3~b$age+b$size+b$pcfat+(1|sex), data=b)))

Why not do machine instruction scheduling in SSA form?
A motivation for scheduling later is that the program representation is closer to the final instruction stream which makes the machine simulation more accurate. If you schedule too early you do not see the instructions produced by phi elimination and the two address fixup pass.
LiveIntervals should work on MachineSSA form. If it doesn't you should file a bugzilla ticket with more details.

Constrain coefs. in linear model to sum to 0
Hello!
I would like to use constrain to sum coeficients of a factor to 0 instead
of classical corner contraint i.e. I would like to fit a model like
lm(y ~ 1 + effectA + effectB)
and say get parameters
intercept
effectA_1
effectA_2
effectB_1
effectB_2
effectB_3
where effectA_1 represents deviation of level A_1 from intercept and
sum(effectA_1, effectA_2) = 0 and the same for factor B.

[Xen-ia64-devel][PATCH] Fix Xen crash when creating VTI in some machines.
Xend will do a hypercall to destory domain when creating VTI guest fail.
If "is_vti"
not be set at this point, HV will call relinquish_vcpu_resource() which
belong
to domU. It may try to free a NULL pointer, so dom0 crash.
This patch fix it.

What's "register pressure set"

I'm looking through codes related to registered pressure tracking, mainly the source files 'RegisterPressure.h/cpp', 'MachineRegisterInfo.h/cpp', 'TargetRegisterInfo.h/cpp'.
There is a concept I can hardly understand, the 'register pressure set'. Class 'TargetRegisterInfo' defines two virtual methods 'getRegClassPressureSets' and

How to write an 'expected failure test'
Hi devs,
I want to write a test that expected to fail. And I want to check the error
message. But I found that if the command exit code is not 0, then the test
will fail. Also, if I add `XFAIL: *`, it will not check the command line
output ... Can someone help me?
Best Regards,
Xing
