mixSPE (version 0.9.3)

rspe: Simulate data from the multivariate skew power exponential distribution.

Description

Simulate data from the multivariate power exponential distribution given the location, scale matrix, shape, and skewness parameter.

Usage

rspe(n, location = rep(0, nrow(scale)), scale = diag(length(location)),
beta = 1, psi = c(0, 0))

Value

A matrix with rows representing the \(p\)-dimensional observations.

Arguments

n

Number of observations to simulate.

location

A \(p\)-dimensional vector. \(\mu\).

scale

A \(p\)-dimensional square scale matrix \(\Sigma\).

beta

A positive shape parameter \(\beta\) that determines the kurtosis of the distribution.

psi

A \(p\)-dimensional vector determining skewness. \(\mu\).
