similar to: Fitting Mixture of Non-Central Student's t Distributions

Dear Ingmar & Dave, Thanks a lot for your help and sorry for the late reply. Finally, I've found a way to separate the mixture of distributions (empirically). But the gamlss package looks great, I'm sure it will help me during my further studies.

Dear all, I am trying to read in big amounts of data with scan. It's only one variable, numeric values, separated by tabs,.. and it's many of them. So I was thinking that I could use the skip option and read in 100000 values at a time - but skip doesn't work, probably because I don't have line breaks in the txt file. So any value specified for skip makes the scan function jump to

Hi, Actually I am facing a similar problem. I would like to fit both an ordinary (symmetric) and a non-central t distribution to my (one-dimensional) data (quite some values.. > 1 mio.). For the symmetric one, fitdistr or funInfoFun (using fitdistr) from the qAnalyst package should do the job, and for the non-central one.. am I right to use gamlss(x ~ 1, family=GT()) ? Anyway, I am a little

Hello, I would like to fit a mixture of two Weibull distributions to my data, estimate the model parameters, and compare the fit of the model to that of a single Weibull distribution. I have used the mix() function in the 'mixdist' package to fit the mixed distribution, and have got the parameter estimates, however, I have not been able to get the log-likelihood for the fit of this model

Dear R developers, The trace of the hat matrix H~(n,n) is computed as follows: tr(H) = tr(BS^-1B') = tr(S^-1B'B) := tr(X) = sum(diag(X)) with B~(n,p), S~(p,p). Since p is of the order 10^3 but S is sparse I would like to employ Taucs linear solver ( http://www.tau.ac.il/~stoledo/taucs/ ) on SX = B'B. (Further improvement by implying a looping over i=1,...,p, calling

Hello I am trying to find an automated way of fitting a mixture of normal and log-normal distributions to data which is clearly bimodal. Here's a simulated example: x.1<-rnorm(6000, 2.4, 0.6)x.2<-rlnorm(10000, 1.3,0.1)X<-c(x.1, x.2) hist(X,100,freq=FALSE, ylim=c(0,1.5))lines(density(x.1), lty=2, lwd=2)lines(density(x.2), lty=2, lwd=2)lines(density(X), lty=4) Currently i am using

Hello, With qpopper you get something like this after a successful login: --- +OK test has 6 visible messages (0 hidden) in 11822 octets. --- This gives a clueful user or support people a quick status about the size of this mailbox, very helpful in full quota scenarios. Would be nice if the next dovecot would have such a feature as well. I doubt the same is (easily) applicable for IMAP (though

Hello, The users here have been migrated to the new mail system with dovecot 0.99.10.5 (Debian package) on the backends. Storage is maildir, only pop3 access for now. I see very seldom occurrences (compared to the session wide pop lock of qpopper on the old system) like this: --- Jun 16 14:35:52 mb01 pop3(user at gol.com): Timeout while waiting for release of exclusive fcntl() lock for index

Hello all, I'm using R2.7.0 (on Windows 2000) and I'm trying do run a robust regression on following model structure: model = "Y ~ x1*x2 / (x3 + x4 + x5 +x6)" where x1 and x2 are both factors (either 1 or 0) and x3.....x6 are numeric. The error code I get when running rlm(as.formula(model), data=daymean) is: error in rlm.default(x, y, weights, method = method, wt.method =

Hello, even though Timo seems to be hibernating (it's not _that_ cold in ole Suomi ;) I'd like to beg for a feature that would be very much appreciated over here. If something like this is already present and eluded my thorough archive and doc searches, feel free to smack me and then point me to the right direction.

Hello, any plans to support this in the future? Seems the inability to use LAST breaks that Yahoo remote mailbox slurper thing, not that I care too much about that, but some mail clients might miss it as well. ;) Regards, Christian Balzer -- Christian Balzer Network/Systems Engineer NOC chibi at gol.com Global OnLine Japan/Fusion Network Services http://www.gol.com/

Hello, running 0.99.10.6 (but seen it before that, too). Also (quite obviously) running 5 auth processes, given the fact that this is a pretty busy box and I didn't want to introduce any artificial bottlenecks. Alas with them eating up half of the free memory (which would go to a much better use as FS cache) I'm getting sorta concerned. If it's not a leak, it's caching something

A time series text with a title that seems designed to hide its wide scope is: Forecasting with Exponential Smoothing The State Space Approach Hyndman, R.J., Koehler, A.B., Ord, J.K., Snyder, R.D. Springer 2009. This book is actually an excellent overview of time series theory, ARIMA as well as state space. It is of course, in part, a manual for the forecast and other packages in what has been

Thanks for the info. I do have one further question for you. On your servers that are currently handling 50k IMAP sessions, how many users does that correspond to? Since many users will have multiple IMAP sessions on multiple devices, I?d like to hear about some real-world numbers that could be used for budgeting a new project like mine. Also, do you use Dovecot IMAP proxies in front of your

Hello, I'm willing to swear that with the 0.99.10.4 Debian package in my rather extensive tests with mailbox format dovecot created not only any missing parental directories but also the INBOX file, but the later I can't prove/test now as I upgraded all respective boxes. However 0.99.10.5 will still create (if needed and possible) missing directories for mbox storage, just not an

Hello All, Has anyone written a function for the distribution function of a *doubly* non-central F-distribution? I looked through the archives, but didn't find anything. Thanks! Wolfgang

Hello all, I would like to fit a mixture model whose components are normal distributions confined in a closed interval. Since there are already several packages for EM, I would like to extend one of these instead of writing a new script from scratch. What would be the best way to customize such an existing package for doing that? Which one is the best in terms of extensibility? (e.g mixtools,
