sample_correlation_matrix: Sample correlation matrix

Description

This function samples a correlation matrix by sampling a covariance matrix from an inverse Wishart distribution and transforming it to a correlation matrix.

Usage

sample_correlation_matrix(dim, df = dim, scale = diag(dim))

Value

A correlation matrix.

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.
