MVtDistribution {distrEllipse}R Documentation

Generating function for MvtDistribution-class

Description

Generates an object of class "MvtDistribution".

Usage

MVt(loc = c(0,0), scale = diag(length(loc)), df = 1, ncp = 0)

Arguments

loc

real number: location / center of the elliptical distribution.

scale

a square matrix (with nrow(scale)==ncol(scale)==length(loc)) of full rank: the / a scale matrix of the elliptical distribution — unique only upto scale%*%t(scale) , i.e. if A1 and A2 are two square matrices of full rank such that A1%*%t(A1)==A2%*%t(A2) , then we obtain the same elliptical distribution for scale = A1 and for scale = A2.

df

integer; degrees of freedom

ncp

positive real number; non-centrality parameter

Value

Object of class "MvtDistribution"
