In curve fitting the power exponential curve (you know a better name?) is used for the so-called 'geometric fit'.

The logarithm of the curve is the prime function approximation.


The curve can be generalized to:

A = e and b = 1/2 gives the Stirling curve which is an approximation for the factorial 1).
Stirling was the one to discover this relation.
