rmultivariate_normal: rmultivariate_normal

In ROOPSD: R Object Oriented Programming for Statistical Distribution

rmultivariate_normal

Description

Generate sample from a multivariate normal distribution. The generator uses a singular values decomposition to draw samples from a normal distribution in the basis of the singular vector. Consequently, the covariance matrix can be singular.

Usage

rmultivariate_normal(n, mean, cov)

Arguments

n	[integer] numbers of samples drawn
mean	[vector] mean of Normal law
cov	[matrix] covariance matrix

Value

[matrix]

Examples

mean = stats::runif( n = 2 , min = -5 , max = 5 )
cov  = ROOPSD::rspd_matrix(2)
X    = ROOPSD::rmultivariate_normal( 10000 , mean , cov )
