...c "sext i32 undef to > i64", and thus also undef? No; sext i32 undef to i64 returns an extraordinary thing. It's a 64-bit value where the low 32 bits are undef, and the high 32 bits are sign extension from whatever bit 31 happened to be. And the low 32 bits in this new value also fluctuate, and the high 31 bits in this value fluctuate with them in concert with bit 31 of the new value. FWIW, you can also get non-bitwise fluctuation, such as (undef*3), which is a value which fluctuates around multiples of 3. Or (undef*3)/5+1, which fluctuates around, well, any value which could be com...

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'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

...ctuating between around 35-55 kbps, the average being 48k. Now suppose I have 10 external listeners connected. 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 ave...

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

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?

...r 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 the optimal lambda value (lambda.1se) which I then use to predict on an independent cohort. What I am finding is that this optimal lambda value fluctuates everytime I run glmnet with LASSO. It deviates quite a bit such that each time I generate an ROC curve for my validation cohort, I get AUC values which deviate a bit. Does anyone know why there is such a fluctuation in the generation of an optimal lambda? I am thinking it might be due to the 10...

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,

...CREF here, but it may actually still be "<ty> addrspace(k)*" where k is specially noted in the datalayout. Semantics: 1. GCREF represents an equivalence class of values (equivalence relation being "points to a fixed semantic object"). The bitwise representation fluctuates constantly outside the compiler's control (the dual of `undef`), but may have invariants (in particular, we'd like to be able to specify alignment, nonnull etc.). At any given point in time all GCREF instances pointing to the same object have the same bitwise representatio...

The thing is that many UPS models will report "on battery" when the voltage fluctuates out of range, but a switching power supply might still be able to coast through it-- especially if the supply is oversized for the load at the time of the abnormality. Since both "outages" (really, the on-battery states) were exactly 10 seconds long means that the UPS was probably tryin...
