Sample covariance matrix

Description

This function samples a covariance matrix from an inverse Wishart distribution.

Usage

sample_covariance_matrix(dim, df = dim, scale = diag(dim), diag = FALSE)

Arguments

dim	[integer(1)] The dimension.
df	[integer(1)] The degrees of freedom of the inverse Wishart distribution greater or equal dim.
scale	[matrix()] The scale covariance matrix of the inverse Wishart distribution of dimension dim.
diag	[logical(1)] Diagonal matrix?

Value

A covariance matrix.
