After some reorganization, we would like to announce the availability on CRAN of a new version (1.6) of our package "distr" as well as the availabilty on CRAN of the new packages "distrEx", "distrSim", "distrTEst", "RandVar".



Changes from 1.5 to 1.6
-[former package "distr"] reorganization:
 we have split up our package distr into smaller units:

Short Descriptions

Short Description of "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 "base" 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.



Short Description of "distrSim":
Classes and methods are provided for a standardized treatment of simulations (also under contaminations) .

Short Description of "distrTEst":
Classes and methods are provided for a standardized treatment of the evaluation of statistical procedures (up to now only estimators) at data/simulations

Short Description of "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, * truncated moments,
* distances between distributions
  (Hellinger, Kolmogorov, total variation, "convex contamination")

* lists of distributions,
* conditional distributions in factorized form 
* conditional expectations in factorized form

-----------------------------------------------------------------------------------------
Short Description of "RandVar":
This package introduces classes and methods for random variables (understood as measurable mappings); in particular groups Math and Arith as well as matrix multiplication and expectations are available so that quite general "regular" expressions with random variables are possible.

We look forward to receiving questions, comments and suggestions
