# Distributions

##### Distributions in the stats package

Density, cumulative distribution function, quantile function and random variate generation for many standard probability distributions are available in the stats package.

- distribution

##### Details

The functions for the density/mass function, cumulative distribution
function, quantile function and random variate generation are named in the
form `dxxx`

, `pxxx`

, `qxxx`

and `rxxx`

respectively. For the beta distribution see `dbeta`

. For the binomial (including Bernoulli) distribution see
`dbinom`

. For the Cauchy distribution see `dcauchy`

. For the chi-squared distribution see `dchisq`

. For the exponential distribution see `dexp`

. For the F distribution see `df`

. For the gamma distribution see `dgamma`

. For the geometric distribution see `dgeom`

. (This is also
a special case of the negative binomial.) For the hypergeometric distribution see `dhyper`

. For the log-normal distribution see `dlnorm`

. For the multinomial distribution see `dmultinom`

. For the negative binomial distribution see `dnbinom`

. For the normal distribution see `dnorm`

. For the Poisson distribution see `dpois`

. For the Student's t distribution see `dt`

. For the uniform distribution see `dunif`

. For the Weibull distribution see `dweibull`

. For less common distributions of test statistics see
`pbirthday`

, `dsignrank`

,
`ptukey`

and `dwilcox`

(and see the
‘See Also’ section of `cor.test`

).
