WebThis can be done by subtracting the sample mean of z ( z ∗ = z − z ¯) and calculating the Cholesky decomposition of z ∗. If L ∗ is the left Cholesky factor, then z ( 0) = ( L ∗) − 1 z ∗ should have sample mean 0 and identity sample covariance. You can then calculate y = L z ( 0) + μ and have a sample with the desired sample moments.
