Dear "stat",

Interesting claim to a name!

In any case, var(X) where X is the data matrix with n rows of 5-variables should do the trick.

Btw, please read the posting guide: your question is legitimate, hiding your identity ("stat stat") is not.

Best wishes,

My question is should I calculate ordinary variance and covariances, taking pairwise variables? or I should take partial covariance between any two variables, keeping other fixed. In my decent opinion is I should go for the second option?
