UnivariateDistribution-class {distr} | R Documentation |

## Class "UnivariateDistribution"

### Description

The UnivariateDistribution-class is the mother-class of the classes AbscontDistribution and DiscreteDistribution.

### Objects from the Class

Objects can be created by calls of the form `new("UnivariateDistribution")`

.

### Slots

`img`

Object of class

`"Reals"`

: the space of the image of this distribution which has dimension 1 and the name "Real Space"`param`

Object of class

`"Parameter"`

: the parameter of this distribution`r`

Object of class

`"function"`

: generates random numbers`d`

Object of class

`"function"`

: density function`p`

Object of class

`"function"`

: cumulative distribution function`q`

Object of class

`"function"`

: quantile function`.withArith`

logical: used internally to issue warnings as to interpretation of arithmetics

`.withSim`

logical: used internally to issue warnings as to accuracy

`.logExact`

logical: used internally to flag the case where there are explicit formulae for the log version of density, cdf, and quantile function

`.lowerExact`

logical: used internally to flag the case where there are explicit formulae for the lower tail version of cdf and quantile function

`Symmetry`

object of class

`"DistributionSymmetry"`

; used internally to avoid unnecessary calculations.

### Extends

Class `"Distribution"`

, directly.
