Compute the beta function (or Euler integral of the first kind), given values of the shape parameters x and y. The beta function is one of the key mathematical functions that are used to compute many of the common statistics upon which analytics studies rely.
Compute the area under the beta function from 0 to x (i.e., the lower incomplete beta function), given values of the shape parameters a and b, and the upper limit of integration x. The incomplete beta function is one of the key mathematical functions that are used to compute many of the common statistics for analytics studies.
Compute the regularized lower incomplete beta function, given values of the shape parameters a and b, and the upper limit of integration x. The incomplete beta function provides a very useful foundation for computing many of the common statistics used in analytics studies.
