Hello. I'm a distro maintainer and was wondering about the efficacy of entropy daemons like haveged and jitterentropyd in qemu-kvm. One of the authors of haveged [0] pointed out if the hardware cycles counter is emulated and deterministic, and thus predictible. He therefore does not recommend using HAVEGE on those systems. Is this the case with KVM's counters?...

Hello everyone, I need to do a sample size calculation. The study two arms and two endpoints. The two arms are two different cancer drugs and the two endpoints reflect efficacy (based on progression free survival) and toxicity. Until now, I have been trying to understand this in terms of a one-arm design, where the acceptable rate of efficacy might be 0.40, the unacceptable rate of efficacy might be 0.20, the acceptable rate of non-toxicity might be 0.85, and the unacce...

On my system a 'time' of make check reports that about 50% of the real time running make check is spent in the OS. This probably also limits the efficacy of attempts to parallelize the test suite, if someone was crazy enough to do that. Using opt -S for tests that end up going to llvm-dis would also be nice. - Daniel

Hello all, This is not a puppet proper issue of course.. but I was wondering if any of you could share some thoughts... When you deploy a system like Puppet at a large park of systems, you instantly increase the efficacy of mistakes and bugs in destroying the environment.... How do you deal with that? I would be interested in any experience or input, especially puppet proper best practices... BTW, does puppet have any means to say something like "don''t ever do anything that takes more than 5 minutes?...

Because DejaGNU limitations? My compiler's test suite is driven by a poor-man's version of DejaGNU (also written on Tcl, but not requiring Expect)...

Statistical activities are commensurately diverse. Some "typical" ones are design and analysis of in vitro and in vivo studies exploring efficacy, pharmacokinetics, and toxicity; design and analysis of high-throughput experiments including genomic, proteomic, and imaging platforms; bioanalytical assay development; optimization of robust antibody fermentation and purification processes; and statistical support to ensure compliance, safety, an...

Hi, I have a problem.... I need help about Generalized Estimating Equation. The response variable is "efficacy" (numeric) and the predictors are "eziology" (categoric) and "terapy" (string). After downloaded the gee from CRAN I tried to use this procedure for example: summary(gee(efficacy~eziology+terapy, id=?, data=pippo, corstr="exchangeable")) Could you send me an exa...

So while this isn't an R issue, I thought some of you might appreciate this brief discussion of the efficacy of pie charts: http://fakescience.tumblr.com/post/6042293374/understanding-pie-charts Sarah -- Sarah Goslee http://www.functionaldiversity.org

Dear all, my aim is to estimate the efficacy over time of a treatment for headache prevention. Data consist of long sequences of repeated binary outcomes (1 if the subject has at least 1 episode of headache , 0 otherwise) on subjects randomized to placebo or treatment. I have fit a logistic regression model with Huber-White cluster sand...

...d. Examples of such applications include inter-procedural register allocation, inter-procedural instruction selection, inter-procedural code layout optimization (I have a colleague working on this using reference affinity theory), and inter-procedural analysis of machine code for measuring the efficacy of compiler transformations for security. Whether one keeps the LLVM IR around or not is orthogonal. What is needed is a way of being able to examine the whole program without having to worry about another transformation running in parallel (if you use a MachineFunctionPass, as I understand i...

...n priority medicines. Among the various working groups, a research program has been started to evaluate biomarkers and disease progression in COPD using longitudinal models. The primary scope of this investigation is to establish which markers of disease have predictive value for the outcome of efficacy trials. Subsequently, modelling will be used to optimise clinical trial design and characterise the relevance of different clinical trial factors and procedures on study power, bias and treatment effect size. Translational aspects will also be explored to allow better extrapolation from precli...

Greetings. I'm trying to determine whether to use rpart or randomForest for a classification tree. Has anybody tested efficacy formally? I've run both and the confusion matrix for rf beats rpart. I've looking at the rf help page and am unable to figure out how to extract the tree. But more than that I'm looking for a more comprehensive user's guide for randomForest including the benefits on using it with MD...

Hi, I can''t find an option of the puppetd client that can just print what the puppetd client will do on my system (updateing files, installing softwares, etc), but without doing all the things (like a "diff" between the current state of my system and the state defined on the puppet server). Is such option exists ? Regards

...looking for two highly motivated scientists (PhD degree) to: 1) investigate disease models in COPD. The COPD project is part of the disease progression working group which consist of two PhD students and two post-doctoral research fellows. 2) evaluate the "operational" efficacy of drugs that have been identified to produce QTc-interval prolongation in early clinical development. The translational research working group will focus on cardiovascular safety, schizophrenia and neuropathic pain. This working group consists in total of six PhD students and two post-doctoral fel...
