Function random_correlation_matrix 

pub fn random_correlation_matrix<R: Rng + ?Sized>(
    dimension: usize,
    rng: &mut R,
) -> Result<DMatrix<f64>>

Generate a random correlation matrix.

Uses the method of Joe (2006) to generate a random correlation matrix that is guaranteed to be positive definite.

Arguments

• dimension - Size of the correlation matrix
• rng - Random number generator

Returns

A random positive definite correlation matrix.

Examples

use copula_core::utils::random_correlation_matrix;

let mut rng = rand::rng();
let corr = random_correlation_matrix(3, &mut rng)?;
assert_eq!(corr.shape(), (3, 3));
