[R] [R-pkgs] New versions for the distr-family of packages, of startupmsg, and a new package "distrDoc"
We would like to announce the availability on CRAN of new versions of our packages "distr" (1.8), "distrEx" (0.4-4), "distrSim" (1.8), "distrTEst" (1.8), "startupmsg" (0.4) as well as a new package "distrDoc" (1.8) [all of them require R >= 2.2.0] ----------------------------------------------------------------------------------------- ********************************* Changes *********************************************** of "distr" (1.8), "distrEx" (0.4-4), "distrSim" (1.8), "distrTEst" (1.8), "startupmsg" (0.4) ***************************************************************************************** ----------------------------------------------------------------------------------------- There are major changes in "distrSim" and "distrTest" from this release on; the more important ones can be inspected at http://www.uni-bayreuth.de/departments/math/org/mathe7/DISTR and the pages linked to on this page. After package installation you may also have a look at NEWS("<pkg-name>") for all the packages mentioned in this mail.>From this version on, we provide a more detailed manual for the distrXXX familyin form of vignette distributed separately in package "distrDoc" (see below). ----------------------------------------------------------------------------------------- Short Descriptions ----------------------------------------------------------------------------------------- ************ "distr": "distr" is to provide a conceptual treatment of random variables (r.v.'s) by means of S4--classes. A virtual mother class "Distribution" is introduced. All distributions of the "stats" package are implemented as subclasses of either "AbscontDistribution" or "DiscreteDistribution". Using these classes, we also provide (default) methods to automatically generate the image distributions under unary mathematical operations as well as a general convolution algorithm. ----------------------------------------------------------------------------------------- ************ "distrSim": Classes and methods are provided for a standardized treatment of simulations (also under contaminations) . ----------------------------------------------------------------------------------------- ************ "distrTEst": Classes and methods are provided for a standardized treatment of the evaluation of statistical procedures (up to now only estimators) at data/simulations ----------------------------------------------------------------------------------------- ************ "distrEx": This package provides some extensions to package "distr" like: * extreme value distribution classes, * expectations +in the form E(X) for the expectation of X where X is some distribution or +in the form E(X,f) for the expectation of f(X) where X is some distribution and f some function in X, * further functionals: var, sd, IQR, mad, median * truncated moments, * distances between distributions (Hellinger, Kolmogorov, total variation, "convex contamination") * lists of distributions, * conditional distributions in factorized form * conditional expectations in factorized form ----------------------------------------------------------------------------------------- ************ "distrDoc": "distrDoc" provides a common vignette to the distrXXX family ----------------------------------------------------------------------------------------- ************ "startupmsg": provides utilities for start-up messages for packages ----------------------------------------------------------------------------------------- We look forward to receiving questions, comments and suggestions Peter Ruckdeschel Matthias Kohl Thomas Stabla Florian Camphausen _______________________________________________ R-packages mailing list R-packages at stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-packages
