Probability Distributions

Probability Distributions and Random Numbers

Listed below are all of the probability distributions available in R and EnvStats. 
 Distributions with a description in bold are new ones that are part of EnvStats. 
 For each distribution, there are functions for generating: values for the probability 
 density function, values for the cumulative distribution function, quantiles, and 
 random numbers.
The data frame <code>Distribution.df</code> contains information about 
 all of these probability distributions.

 package

Graphical and statistical analyses of environmental data, with
focus on analyzing chemical concentrations and physical parameters, usually in
the context of mandated environmental monitoring. Major environmental
statistical methods found in the literature and regulatory guidance documents,
with extensive help that explains what these methods do, how to use them,
and where to find them in the literature. Numerous built-in data sets from
regulatory guidance documents and environmental statistics literature. Includes
scripts reproducing analyses presented in the book "EnvStats: An R Package for
Environmental Statistics" (Millard, 2013, Springer, ISBN 978-1-4614-8455-4,
<https://link.springer.com/book/10.1007/978-1-4614-8456-1>).
