EmpiricalMVDistribution: Generating function for mulitvariate discrete distribution

In distrEx: Extensions of Package 'distr'

Generating function for mulitvariate discrete distribution

Description

Generates an object of class "DiscreteMVDistribution".

Usage

EmpiricalMVDistribution(data, Symmetry = NoSymmetry())

Arguments

data	numeric matrix with data where the rows are interpreted as observations.
Symmetry	you may help R in calculations if you tell it whether the distribution is non-symmetric (default) or symmetric with respect to a center.

Details

The function is a simple utility function providing a wrapper to the generating function DiscreteMVDistribution.

Typical usages are

    EmpiricalMVDistribution(data)
  

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

Value

Object of class "DiscreteMVDistribution"

X <- matrix(rnorm(50), ncol = 5)

## empirical distribution of X
D1 <- EmpiricalMVDistribution(data = X)
support(D1)
r(D1)(10)
