request for comments --- package "distr" --- S4 Classes for Distributions
...stributions of the " base" package for which such "r", "d", "p",
and "q"
functions exist are implemented (essentially by wrappers of the
origininal code)
as subclasses of either of the two the subclasses "AbscontDistribution" or
" DiscreteDistribution".
This approach seems very appealing to us from a conceptual viewpoint:
Just pass an object of some derived distribution class to a generic
function as
argument and let the dispatching mechanism decide what to do on run-time.
As an example, we may automatically generate new objects of...

New package: distr
...istr .
It 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.
Additionally, we also provide classes for a standardized treatment of
simulations (also under contaminati...

New user: Custom probability distribution
Hello,
Given a probability function: p(x) = 12 / (25(x+1)) , x=0, 1, 2, 3 we
generate the following values:
C1 C2
0 0.48
1 0.24
2 0.16
3 0.12
Now, I'm supposed to create 50 random values using this table. In
MiniTab, I simply selected Calc -> Random Data -> Discrete, and selected
the columns, and it created 50 random values in a new column.[1]
How do I do the
