Emprical argument in mvrnorm function from the R package 'MASS' I'm just wondering what is the difference between empirical = TRUE or FALSE when simulating normally distributed multivariate. Is it that when empirical = TRUE every simulated data will indicate the identical preset covariance matrix?

"If true, mu and Sigma specify the empirical not population mean and covariance matrix." (from mvrnorm documentation)
Meaning that if TRUE, the covariance matrix would be as specified
