Hi all,

Some question about covariance matrix and Wishart dist.
I've a theorical covariance matrix S.
Suppose X RandomNormal(N,p)*CholDecomposition(S) a random correlated
- What is the theoretical distribution of X covariance (Wishart(S,nobs)?)
- How can I test whether an observed covariance (from a sample size) follow
the theoretical distribution.

Thanks & Best Regards
