Returns the natural logarithm of the gamma function of
x:
ln(Γ(x)).
The gamma function is an extension of the factorial function that works on all positive values of
x.
If
n
is a positive integer, then:
Γ(n) = (n - 1)!.
The
gammaLog
function may be useful in System Dynamics models for computing combinatorial factors.
