DiscreteMVDistribution: Generating function for DiscreteMVDistribution-class

Description

Generates an object of class "DiscreteMVDistribution".

Usage

DiscreteMVDistribution(supp, prob, Symmetry = NoSymmetry())

Arguments

supp

numeric matrix whose rows form the support of the discrete multivariate distribution.

prob

vector of probability weights for the elements of supp.

Symmetry

you may help Rin calculations if you tell it whether the distribution is non-symmetric (default) or symmetric with respect to a center.

Value

• Object of class "DiscreteMVDistribution"

concept

• multivariate distribution
• discrete distribution
• S4 distribution class
• generating function

Details

Typical usages are DiscreteMVDistribution(supp, prob) DiscreteMVDistribution(supp) Identical rows are collapsed to unique support values. If prob is missing, all elements in supp are equally weighted.

Examples

# Dirac-measure at (0,0,0)
D1 <- DiscreteMVDistribution(supp = c(0,0,0))
support(D1)

# simple discrete distribution
D2 <- DiscreteMVDistribution(supp = matrix(c(0,1,0,2,2,1,1,0), ncol=2), 
                prob = c(0.3, 0.2, 0.2, 0.3))
support(D2)
