The beta function ( B(x, y) ) and the gamma function ( \Gamma(z) ) are closely related through the formula ( B(x, y) = \frac{\Gamma(x) \Gamma(y)}{\Gamma(x + y)} ). The beta function can be interpreted as a normalization of the product of two gamma functions. Additionally, the beta function can be expressed as a definite integral, which also reflects its relationship with the gamma function. This connection is particularly useful in various areas of mathematics, including probability and statistics.

How the cdf of binomial distribution is calculated by incomplete gamma function?

The cumulative distribution function (CDF) of the binomial distribution can be expressed using the incomplete gamma function by relating it to the probability mass function (PMF). The binomial CDF sums the probabilities of obtaining up to ( k ) successes in ( n ) trials, which can be represented by the incomplete beta function. Since the incomplete beta function is related to the incomplete gamma function, the binomial CDF can ultimately be computed using the incomplete gamma function through the transformation of variables and appropriate scaling. Thus, the CDF ( F(k; n, p) ) can be calculated as ( F(k; n, p) = I_{p}(k+1, n-k) ), where ( I_{p} ) is the regularized incomplete beta function, which can also be expressed in terms of the incomplete gamma function.
