Ibetaib() Function Ibetaib ( A As  Double, X As  Double, P As  Double, Optional Info As  Long  ) Inverse function of b for normalized incomplete beta function Ix(a, b) Purpose Computes the inverse function of b for normalized incomplete beta function Ix(a, b). Returns Double Inverse function of b for normalized incomplete beta function Ix(a, b). Parameters [in] A Argument a. (A > 0) [in] X Argument x. (0 < X < 1) [in] P Value of Ix(a, b). (0 <= P <= 1) [out] Info (Optional) = 0: Successful exit. = -1: The argument A had an illegal value. (A <= 0) = -2: The argument X had an illegal value. (X <= 0 or X >= 1) = -3: The argument P had an illegal value. (P < 0 or P > 1) = 1: Floating point range error. Reference boost/math/special_functions
