## Multivariate Distributions

### Description

The class of multivariate distributions. One has at least to
specify the image space of the distribution and a function generating
(pseudo-)random numbers. The slot `q`

is usually filled with
`NULL`

for dimensions `> 1`

.

### Objects from the Class

Objects can be created by calls of the form `new("MultivariateDistribution", ...)`

.

### Slots

`img`

Object of class `"rSpace"`

.
Image space of the distribution. Usually an object of
class `"EuclideanSpace"`

.

`param`

Object of class `"OptionalParameter"`

.
Optional parameter of the multivariate distribution.

`r`

Object of class `"function"`

:
generates (pseudo-)random numbers

`d`

Object of class `"OptionalFunction"`

:
optional density function

`p`

Object of class `"OptionalFunction"`

:
optional cumulative distribution function

`q`

Object of class `"OptionalFunction"`

:
optional 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.

### Methods

- show
`signature(object = "MultivariateDistribution")`

- plot
`signature(object = "MultivariateDistribution")`
