Hello: Could anyone point me to a nice example where someone has created methods for "[" on a user defined Class? I looked at the package Matrix but that was a little daunting. I'm looking for someone a little more introductory. I've tried to search the help section and the web but its difficult since "[" isn't searchable. Thanks in advance! Greg [[alternative

Dear useRs, A new version of actuar is available since last Friday. This is mainly a bugfix release. From the NEWS file: Version 1.0-2 ============= USER-VISIBLE CHANGES o m<foo>() and lev<foo>() now return Inf instead of NaN for infinite moments. (Thanks to David Humke for the idea.)

Dear useRs, I'm happy to announce a substantial update of package actuar that bumps the version number to 2.0-0. This release focuses on additional support for continuous and discrete distributions, new functions to simulate data from compound models and mixtures, and revised and improved documentation.

...los genera_ es la log-logistica. Haciendo una revisión de los datos y las aplicaciones de esta distribución, encuentro que sería apropiado utilizarla como modelo. En R es posible generar observaciones, densidades, percentiles y algunas otras cantidades para esta distribución utilizando la libreria actuar (ver [2]). Me gustaria saber si alguno de ustedes conoce alguna función (ya implementada en R o que haya escrito y quiera/pueda compartirla) que permita estimar *los parámetros* de la distribución log-logística. Muchisimas gracias, Jorge Ivan Velez [1] https://stat.ethz.ch/pipermail/r-help-es/2...

UseRs, Version 0.9-4 of actuar should be making its way to CRAN mirrors. The main highlights of this new version are speed enhancements for a few functions, support for phase-type distributions and functions for ruin theory.

Dear developeRs, Compilation of the latest version (0.9-5) of my actuar package fails with r-release MacOS_X ix86 on CRAN; see http://www.R-project.org/nosvn/R.check/r-release-macosx-ix86/actuar-00check.html All errors come from accented letters in comments in latin-1 encoded files (except hierarc.R which is in UTF-8, my bad). Encoding is declared as latin-1 i...

Dear all, I have the cdf of the following power fuction distribution: F(y)=(y/350)^a               ,0<y<350, where " a " is some parameter with range a>0. I want to use it as the argument of the discretize function of the actuar package. So I think I need to define this function to R so that if I entered a=1, I get the following F(y)=(y/350) and if I entered a=4.5, I get the following F(y) =(y/350)^4.5 ........... and so on I've tried a<-vector(mode="numeric",length=1) powercdf<-function(a,y) (y/350...

http://r.789695.n4.nabble.com/file/n3216865/Inverse_Gamma.png Hello, I am seeking help in estimating the parameters of an inverse gamma distribution (from the 'actuar' package) using a function like 'fitdistr'. Unfortunately I haven't found such a package using findFn('fit Inverse Gamma') from the 'sos' package and was therefore hoping someone might be aware of such a function? Secondly, is there a way to shift the pdf (code b...

Hi. I was trying to calculate 2. order moment for a loggamma sample. Also, I checked it with the function mlgamma from the package actuar, which calculates moments based on loggamma parameters. Se below - I get big deviations. Numerical integration suggests that mlgamma gets it right. What fails in my attempt to use SLLN to estimate the 2. order moments? Code: sum(rlgamma(10^6,25,2.6)^2)/10^6 #Estimation by SLLN [1] 1.964011e+13 &...
