WebNormal Distribution Overview. The normal distribution, sometimes called the Gaussian distribution, is a two-parameter family of curves. The usual justification for using the normal distribution for modeling is the Central Limit theorem, which states (roughly) that the sum of independent samples from any distribution with finite mean and variance converges to … WebIt appears that you're asking how to generate data with a particular correlation matrix. A useful fact is that if you have a random vector x with covariance matrix Σ, then the random vector A x has mean A E ( x) and covariance matrix Ω = A Σ A T. So, if you start with data that has mean zero, multiplying by A will not change that, so your ...
