Hi all, In a recent IISWC paper <http://groups.csail.mit.edu/commit/papers/19/ithemal-measurement.pdf>, we've proposed BHive - a new methodology for benchmarking arbitrary basic blocks that has several advantages over the one currently used in llvm-exegesis. In particular, the new methodology: - automatically handles memory accesses in the basic block, without the need to manually annotate live-ins, - maps all memory addresses accessed by t...

Good afternoon! As mentioned in the subject, my question regards more the methodological part that accompanies survey design and the statistical part that is involved. So, I have the following data: a<-data.frame (id_hh=c(1:5), strata=c(1,1,2,2,1), Nhstrata=c(100,100,200,200,100), Nrmemb=c(2,4,2,5,4)) a$ocmemb1<-c("wk","jl","st","jl","st")

Fisher is not the only person that it may be necessary to read 4 or 5 times. The same may be the case for side comments that Bill Venables is wont to make. Now to the parallel universe that I have in mind. I wonder whether the time is opportune for a list that focuses on "Statistical Methodology for R Users". The difference from other statistical methodology lists is that it will be assumed that list members have contact with, and an interest in, R. So the appearance of R code, and references to R documentation, would be entirely in place. One of the great things about R, and this...

I tried a bunch of tools and ended up using Jakarta J-Meter b/c it works cross-platform (Unix/Windows in my situation) and has a gui which shallows the learning curve. I''ve been quite satisfied with it.. Search the archives on this list and you should be able to find some great info Zed and others wrote a while back on How to Load Test Correctly.

...tised) build end-to-end for several days now. The majority of the fun has been coming from vendor packages (no names mentioned), typically with conflicting permissions on files, or perhaps different home directories, UIDs for the app users so it matters in which order you do things in. My current methodology is to go through things linearly. Install the packages, check for dependencies, check for directories and (config) files, users etc and write the manifests manually. I''m pretty liberal putting dependencies into my manifests. However you just can''t spot all of them easily. Thes...

Dear all, I am attempting to use RSM in order to optimise the analysis of volatile compounds. After changing two variables and performing a series of measurements, I get the following: X1 X2 resp 1 -0.8 -1.0 1101039 2 -0.8 0.0 809947 3 -0.8 1.0 814664 4 0.0 -1.4 759484 5 0.0 0.0 665916 6 0.0 0.0 654054 7 0.0 0.0 641134 8 0.0 0.0 673143 9 0.0 0.0

Hi all, I have a question regarding how to properly analyze a data set and then how to perform the analysis in R. First, I have data that I would like to analyze using a mixed GLM (I think this is the most appropriate method, but I am unsure). In a mixed model (y = X*beta+Z*gamma+epsilon), I would like to structure the variance matrices of gamma, G, and the error, R, to take advantage of all my

Hi, I am running a learning experiment in which both training subjects and controls complete a pretest and posttest. All analyses are being conducted in R. We are looking to compare two training methodologies, and so have run this experiment twice, once with each methodology. Methodology is a between-subjects factor. Trying to run this analysis with every factor included (ie, subject as a random factor, session nested within group nested within experiment) seems to me (after having tried) to be clumsy and probably uninterpretable. My favoured model for the analysi...

One of the outcomes of useR! 2006 is that JSS is planning to publish a series of special volumes. They will be guest edited (I have guest editors already, although somewhat tentative in some cases). Each volume will have 5-10 issues (articles) of the usual JSS format. Psychometrics in R Political Methodology in R Econometrics in R Social Science Methodology in R Spectroscopy/Chemometrics in R Ecology in R If you have suggestions, comments, possible contributions, ideas for additional volumes and so on, send them to me and I'll forward them to the appropriate authorities. -- Jan de Leeuw; Disting...

Hi there, I am currently working on my dissertation which is about testing the martingale hypothesis in the stock market using a methodology involving a range of variance ratio tests and multiple variance ratio tests. I contacted the author of a reference paper and I was told that the tests can be conducted using R programming language. Although I have gone through the theoretical background of the methodology, but I found it quite diff...

...ies may be categorical or anyway non-numerical variables (e.g. the fact of belonging/not belonging to a certain group; joining/not joining a certain treaty etc...). I have seen some data clustering examples, but without categorical variables and I wonder if this is an inherent limitation of the methodology (on the top of my head, I would not know how to define the distance between non-numerical variables). Any suggestions about the general methodology and R packages/code snippets is really appreciated. And also: do the units in which I express a statistical indicator play a role? For instance: fo...
