unonr {mnonr}

Multivariate Non-normal Random Number Generator based on Marginal Measures (Vale and Maurelli's method)

Description

Generate Multivariate Non-normal Data using Vale and Maurelli (1983) method. The codes are copied from mvrnonnorm function in the semTools package.

Usage

unonr(n, mu, Sigma, skewness = NULL, kurtosis = NULL, empirical = FALSE)

Arguments

n

Sample size

mu

A mean vector

Sigma

A covariance matrix

skewness

A skewness vector

kurtosis

A kurtosis vector

empirical

If TRUE, mu and Sigma specify the empirical not population mean and covariance matrix

Value

A data matrix (multivariate data)

Examples

unonr(1000, c(1, 2), matrix(c(10, 2, 2, 5), 2, 2), skewness = c(1, 2), kurtosis = c(3, 8))
