Dear all, Has anyone worked on coding for calculating Lyapunov Exponent for a time series data? or any package is available for computing Lyapunov? Please advice and many thanks in advance. Catherine X Wang

Hello, Does anybody know if there is somewhere in R a function to calculate the Lyapunov exponent in a time series?

Hello, I am trying to collect several global measures or statistics for time-series as well as packages of R that can compute them. I have found several of them in papers and books, but the literature is so big i am sure i am missing several of them. skewness kurtosis min max mean SD trend seasonality periodicity chaos (Lyapunov Exponent) / Largest Lyapunov Exponent (i think is the same

Dear Sir, I’am a frensh student and i’am a new user of the R software. After using the command (x<-read.delim(“clipboard”) to read a spreadsheet of Excel, I want to run the bds test and calculate the Lyapunov exponent. I have charged the R software by the packages tseries and tseriesChaos. when i run bds.test(x,m=2) Unfortunately the R software displays “error in as.vector(x,mode= “double”) :

ACM Software Copyright and License Agreement I have often seen the use of routines from the ACM Collected Algorithms, i.e. <netlib.org/toms/> (CALGO, or Trans. On Math.

The use of these CALGO

I've noticed that a few people here are from Australia. I'm wondering where you all get your hardware from. I'll probably order some of the X100P cards from Digium soon (and possibly some FXO cards), but for other things such as ATAs, etc. However - these obviously aren't ACA compliant. Does anybody know of compatible hardware (for POTS lines) that is ACA compliant? The cheapest

Hi, Does somebody knows of the existence of a library of functions for solving differential equations, I need a solver for a system of non linear first order differential equations. I think there was something in IMSL but that was a long time ago and probably there are some new algorithms in the new now. Thanks for any pointers. . R.

I want to ascertain the basis of the table ranking, i.e. the meaning of "extreme", in Fisher's Exact Test as implemented in 'fisher.test', when applied to RxC tables which are larger than 2x2. One can summarise a strategy for the test as 1) For each table compatible with the margins of the observed table, compute the probability of this table conditional on the

I sometimes wonder how difficult it would be to set up an email system, like the netlib@netlib.bell-labs.com facility for f2c, but for producing binary versions of packages. Has anyone every thought about this? I guess the main use would be for Windows, about which I know almost nothing, so I won't volunteer myself. Paul Gilbert

Hi. I just noticed the paper by Morales and Nocedal Remark on "Algorithm 778: L-BFGS-B: Fortran Subroutines for Large-Scale Bound Constrained Optimization". TOMS 2011; 38(1): 7 http://www.ece.northwestern.edu/~morales/PSfiles/acm-remark.pdf which describes a couple of improvements (speed and accuracy) to the original Netlib code which AFAICT is that still used by optim() via f2c.

Hello, I have only negative experiences with cpp-netlib - I would not recommend it. If the discussion was around only the client part I think libcURL would be the best option since it's available everywhere and is a well maintained library. But as you mention it's only the client part. We use pion (https://github.com/splunk/pion) to build a HTTP server interface, but since it seems

Hi R-Users I need to estimate Lyapunov exponent of my time series. After reading description of all functions available I still don't know how to determine time delay. My time series length is 4200. Is it possible to determine time delay with other function's output or I can choose any random value? Thanks for your help! -- View this message in context:

Hello. I'm solving ODEs in R. I need "as many methods as possible", so I downloaded the Fortran functions from http://www.netlib.org/ode/. Then I created DLLs and dyn.loaded them to R. Problem is that I don't know how to use them. I've been trying for many days and can't solve it. So I would be very glad if you could give me some link (or whatever) where I can see how to

No se bien si hacer la pregunta aca, pero en la lista de correo de bioconductor he tenido algunos problemas para hacer la consulta. Por un error actualice R de la version 15.0.3 a la 3.0.2, y ahora no me corren las librerias de bioconductor. Al intentar usar alguna me aparece el mensaje : Your Bioconductor is out-of-date, upgrade to version 2.13 by following instructions at

I often use Lyx/Sweave and I typically write in english. Today I had to write a document in Italian and, as many of you know, many italian popular words use ?, ?, ?. ?, etc. I discovered that if I type in Italian (that is there is at least one letter with accent) with the Sweave module selected lye is not able to correctly compile the document. I tried to change the input encoding, but it
