distrEx provides some extensions of package distr:
expectations in the form
E(X)
for the expectation of a
distribution object X
E(X,f)
for the expectation of f(X)
where X
is some distribution object and
f
some function in X
further functionals: var, sd, IQR, mad, median, skewness, kurtosis
truncated moments,
distances between distributions (Hellinger, Cramer von Mises, Kolmogorov, total variation, "convex contamination")
lists of distributions,
conditional distributions in factorized form
conditional expectations in factorized form
Support for extreme value distributions has moved to package RobExtremes

Demos are available — see demo(package="distrEx")

G. Jay Kerns, gkerns@ysu.edu, has provided a major contribution,
in particular the functionals skewness
and kurtosis
are due to him.
Natalyia Horbenko, natalyia.horbenko@itwm.fraunhofer.de has ported
the actuar code for the Pareto distribution to this setup.
You may suppress the startup banner/message completely by setting
options("StartupBanner"="off")
somewhere before loading this package by
library
or require
in your Rcode / Rsession.
If option "StartupBanner"
is not defined (default) or setting
options("StartupBanner"=NULL)
or
options("StartupBanner"="complete")
the complete startup banner is
displayed.
For any other value of option "StartupBanner"
(i.e., not in
c(NULL,"off","complete")
) only the version information is displayed.
The same can be achieved by wrapping the library
or require
call
into either suppressStartupMessages()
or
onlytypeStartupMessages(.,atypes="version")
.
As for general packageStartupMessage
's, you may also suppress all
the startup banner by wrapping the library
or require
call into suppressPackageStartupMessages()
from
startupmsgversion 0.5 on.
Note: The first two numbers of package versions do not necessarily reflect packageindividual development, but rather are chosen for the distrXXX family as a whole in order to ease updating "depends" information.
Some functions of package stats have intentionally been masked, but
completely retain their functionality — see distrExMASK()
.
If any of the packages e1071, moments, fBasics is to be used
together with distrEx the latter must be attached after any of the
first mentioned. Otherwise kurtosis()
and skewness()
defined as methods in distrEx may get masked.
To remask, you
may use kurtosis < distrEx::kurtosis; skewness < distrEx::skewness
.
