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! R. [[alternative HTML version

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. Is

[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. Signed-off-by, Zhang Xin < xing.z.zhang@intel.com > Good good study,day day up ! ^_^ -Wing(zhang xin) OTC,Intel Corporation

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 -------------- next part -------------- An HTML attachment was scrubbed... URL:
