R: Multivariate Distributions

MultivariateDistribution-class {distrEx} | R Documentation

## 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

  `signature(object = "MultivariateDistribution")`
