Distributions in thestats Package

Description

Density, cumulative distribution function, quantile function and randomvariate generation for many standard probability distributions areavailable in thestats package.

Details

The functions for the density/mass function, cumulative distributionfunction, quantile function and random variate generation are named in theformdxxx,pxxx,qxxx andrxxx respectively.

For the beta distribution seedbeta.

For the binomial (including Bernoulli) distribution seedbinom.

For the Cauchy distribution seedcauchy.

For the chi-squared distribution seedchisq.

For the exponential distribution seedexp.

For the F distribution seedf.
