Density of a MSEN distribution

Description

Density of a MSEN distribution

Usage

dmsen(x, mu = rep(0, d), Sigma, theta = Inf, formula = "direct")

Arguments

x

A data matrix with n rows and d columns, being n the number of data points and d the data the dimensionality.

mu

A vector of length d representing the mean value.

Sigma

A symmetric positive-definite matrix representing the scale matrix of the distribution.

theta

A number greater than 0 indicating the tailedness parameter.

formula

Method used to calculate the density: "direct", "indirect", "series".

Value

The value(s) of the density in x

Examples

d <- 3
x <- matrix(rnorm(d*2), 2, d)
