Most often it is defined re- cursively with the initial value at 0 equaling 1 and the ratio of this function for x divided by this function for the quan- tity x minus one equaling x.
This term is used to describe experiments in which at least two factors are tested at all of their possible levels. It more commonly refers to a function which for large values can be estimated by the Stirling approximation. For posi- tive integers, this function shifted to the right by one unit is equal to the gamma function. Most often it is defined re- cursively with the initial value at 0 equaling 1 and the ratio of this function for x divided by this function for the quan- tity x minus one equaling x. This function is often used in combinatorics in the formulas for combinations and permu- tations. Give the name of the function that, for a natural number n, equals the product of all the numbers from 1 to n.
