Dear R-users, Has anyone written a function for multifractal detrended fluctuation analysis? The "fractal" package does mono-fractal DFA, but not multifractal as far as I can tell. The MF-DFA approach is presented in: J. W. Kantelhardt, S. Zschiegner, E. Koscielny-Bunde, S. Havlin, A. Bunde, and H. E. Stanley, "Multifractal Detrended Fluctuation Analysis of

I am trying to get a TrippLite SU1500RTXL2Ua working with nut on Mandriva 2007.1, is there a particular version of nut needed to get this to work? At first I tried nut 2.0.5 (which came with 2007.1) but it wouldn't work, and then research showed it was an older version of nut. So nut-2.2.1-2 src rpm was pulled from Mandriva 2008.1, the binary rpm built, and nut and nut-server installed from

I'm working with the DFA (detrended fluctuation analysis) function in the package fractal on postural sway data, and for the life of me can't get the results to turn out as they should given what my data looks like. The data resemble a random walk, but the Hurst exponent estimates that I'm getting at ~0.9 instead of ~1.4, which is the value a researcher I've been working with

...onnected. How much bandwidth will they need/use? Common sense says: average bitrate * 10 = 480kbps (plus any overheads) Here's the question: If I have 10 listeners connected, and the bitrate fluctuates up to 55kbps, then is the actual bandwidth requirement at that instant 550kbps? Or are the fluctuations more rapid than I can appreciate from the Winamp display? Or to put it another way, over what period of time is the average bitrate calculated, and is this period significant in terms of average buffer size? Also just quickly - could the external authentication mechanism be used to reject new...

Good afternoon, my name is Gorka Merino and i am a scientist working in the Marine Science Institune in Barcelone. I'm interested in the application of "Detrended Fluctuation Analysis" (DFA) with the R packages. I've tried to obtain some information related to DFA from the 'Help' options but failed. Could somebody inform me about the use of these techniques in R

Hi all, Has anyone tested for FA in R? I need to seperate out the variance due to measurement error from variation between individuals (following Palmer & Strobeck 1986).

In order to improve the performance of fsync, we use the outstanding ordered extents to avoid looking up the checksum from the csum tree. But we didn''t filter out the ordered extents whose csum is still being calculated, when we got those ordered extents, we had to wait for the csum calculation. It made the performance dropped down suddenly. (On my box, it drop down from 56MB/s to

Unless your code changes algorithm, you don't need to worry too much about performance fluctuations caused by that change. This may vary on compiler, compiler version, code around your change, and test cases. -------------- next part -------------- An HTML attachment was scrubbed...

Dear useRs, the strucchange package for testing for structural change has been updated: the current version is 1.2-4. The most significant additions were two functions gefp() and efpFunctional(). gefp() implements a class of generalized M-fluctuation tests for testing for parameter instability or structural change in general parametric models including generalized linear models (GLMs).

Hi All I was using the DFA() in the fractal package to examine a set of time series data. And I was not sure what the H estimate meant from the summary table. is it the alpha of the power law equation?

Hi all, I am using the glmnet R package to run LASSO with binary logistic regression. I have over 290 samples with outcome data (0 for alive, 1 for dead) and over 230 predictor variables. I currently using LASSO to reduce the number of predictor variables. I am using the cv.glmnet function to do 10-fold cross validation on a sequence of lambda values which I let glmnet determine. I then take

hi all we're using rsync to backup our web server at the moment using it in a cron job the server we are using to receive all the sync files is a live but not heavily used linux machine but rsync still takes up more resources than we want it to it takes up to 95% (fluctuating) cpu load and a fair bit of memory too the cron job uses nice -19 rsync but that doesn't seem to do anything,

This is a proposal to add strong GC reference types to LLVM. We have some local (downstream) patches that are needed to prevent LLVM's optimizer from making transforms that are problematic in the presence of a precise relocating GC. Adding a notion of a strong GC reference to LLVM will let us upstream these patches in a principled manner, and will act as a measure to avoid new problematic
