This question seems to be more maths or statistics than physics, and more appropriate for math.stackexchange.com or stats.stackexchange.com . – Frédéric Grosshans Oct 18 '12 at 14:13
Move this to statistics. It seems that the formula for the 4th cumulant is asked for. – Arnold Neumaier Oct 18 '12 at 16:35

Questions on Physics Stack Exchange are expected to relate to physics within the scope defined in the FAQ. Consider editing the question or leaving comments for improvement if you believe the question can be reworded to fit within the scope. Read more about closed questions here.

See http://en.wikipedia.org/wiki/Cumulant, joint cumulants. There is a general formula for $n$ variables there that should not be difficult to compute for the special case of $n=4$.
