DiscreteMVDistribution-class: Discrete Multivariate Distributions

Description

The class of discrete multivariate distributions.

Objects from the Class

Objects can be created by calls of the form new("DiscreteMVDistribution", ...). More frequently they are created via the generating function DiscreteMVDistribution.

Extends

Class "MultivariateDistribution", directly. Class "Distribution", by class "MultivariateDistribution".

r(D1)(5)

(D2 <- DiscreteMVDistribution(supp = matrix(c(1:5, rep(3, 5)), ncol=2, byrow=TRUE)))
support(D2)
r(D2)(10)
d(D2)(support(D2))
p(D2)(lower = c(1,1), upper = c(3,3))
q(D2)
param(D2)
img(D2)

e1 <- E(D2) # expectation
