Please the footer of this message. It works for me, and we need the
'at a minimum' information we asked for to begin to guess what might
be wrong for you.
However, this is pretty much overkill: there is nothing 'mutlivariate'
about your example, and even if there were mean() and var() give the
standard parameter estimates.
