Now, we successfully expanded factorial to the entire complex plane except at negative integers, but Gamma function has some other brilliant properties. Let's have a look at some of them: Alternative Definition for Euler-Mascheroni constant From the last article, we know that Euler-Mascheroni cons...

The gamma function Γ(x) generalizes the factorial function to the positive real numbers and is defined as integral from 0 to ∞ of t¹⁻ˣ⋅e⁻ᵗ𝑑tThe gamma function has the property that for all positive real numbers x, Γ(x + 1) = x⋅Γ(x), such that the ...
11.4.1 Factorial moments From the above, the factorial moments and the probabilities F(n) can be calculated with a procedure similar to the case of the neutrons, although the expressions will be somewhat more involved. In order to simplify notations and expedite the interpretation of certain freq...

Data sets were tested for normality using Kolmogorov-Smirnov test and then compared with the appropriate test (t-test or Wilcoxon two-sided rank test). Statistical significance of data for protocols with factorial design (i.e., light on/off conditions) were assessed using two-way repeated-measur...
The Gamma function is very tightly linked to the notion of factorial. Hence, before moving on to the Gamma function properties, let us first recall what the factorial is. Factorial operator Let n be a positive integer. The factorial of n (denoted by n!) is the product of all integers be...
