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

Extends

Class "Distribution", directly.

Methods

initialize
signature(.Object = "UnivariateDistribution"):

initialize method

dim
signature(x = "UnivariateDistribution"):

returns the dimension of the support of the distribution

-
signature(e1 = "UnivariateDistribution"):

application of `-' to this univariate distribution

*
signature(e1 = "UnivariateDistribution", e2 = "numeric"):

multiplication of this univariate distribution by an object of class `numeric'

/
signature(e1 = "UnivariateDistribution", e2 = "numeric"):

division of this univariate distribution by an object of class `numeric'

+
signature(e1 = "UnivariateDistribution", e2 = "numeric"):

addition of this univariate distribution to an object of class `numeric'

-
signature(e1 = "UnivariateDistribution", e2 = "numeric"):

subtraction of an object of class `numeric' from this univariate distribution

*
signature(e1 = "numeric", e2 = "UnivariateDistribution"):

multiplication of this univariate distribution by an object of class `numeric'

+
signature(e1 = "numeric", e2 = "UnivariateDistribution"):

addition of this univariate distribution to an object of class `numeric'

-
signature(e1 = "numeric", e2 = "UnivariateDistribution"):

subtraction of this univariate distribution from an object of class `numeric'

+
signature(e1 = "UnivariateDistribution", e2 = "UnivariateDistribution"):

Convolution of two univariate distributions. The slots p, d and q are approximated by grids.
