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:
* "distr" now only contains the (basic) classes and methods
for distributions
* "distrSim" requires "distr" and contains classes and methods
for data / simulations formerly contained in "distr"
* "distrTEst" requires "distr" and "distrSim" and contains
classes and methods for evaluation of estimators
at data / simulations formerly contained in "distr"
-[distrSim] under the hood: signature of method "simulate" adapted
in order to prevent collision with corresponding method
from the stats package
some more details to be found at
http://www.uni-bayreuth.de/departments/math/org/mathe7/DISTR
a more detailed manual is available at
http://www.uni-bayreuth.de/departments/math/org/mathe7/DISTR/distr.pdf
-additional packages by Matthias Kohl:
* "distrEx" requires "distr" and contains some extensions to
package "distr" (see later)
* "RandVar" requires "distr" and "distrEx" and contains classes
and methods for random variables (see later)
These two packages are described in some detail in Matthias' PhD Thesis
"Numerical Contributions to the Asymptotic Theory of Robustness", App. D
available on http://stamats.de/ThesisMKohl.pdf

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.
