I was completely on the wrong way, and tried to find a solution with
the formula instead to substitute the formula.
So I tried to implement pchisq into the formula - and of course I
got wrong values ...
> p <- function(x) ((0.5^(5/2))/gamma(5/2))*(x^((5/2)-1))*
(2.718281828459^(-x/2))

0.0001111 with absolute error < 2.7e-05
Check result>>>>
