Ibetaci() Function Ibetaci ( A As  Double, B As  Double, Q As  Double, Py As  Double, Optional Info As  Long  ) Inverse function of x for normalized compliment of incomplete beta function 1 - Ix(a, b) Purpose Computes the inverse function of x for normalized compliment of incomplete beta function 1 - Ix(a, b). Returns Double Inverse function of x for normalized compliment of incomplete beta function 1 - Ix(a, b). Parameters [in] A Argument a. (A > 0) [in] B Argument b. (B > 0) [in] Q Value of 1 - Ix(a, b). (0 <= Q <= 1) [out] Py 1 - x is returned. The value returned in Py is free from cancellation errors. Even if Ibetaci returns 1, the value of Py may be non-zero very small value. [out] Info (Optional) = 0: Successful exit. = -1: The argument A had an illegal value. (A <= 0) = -2: The argument B had an illegal value. (B <= 0) = -3: The argument Q had an illegal value. (Q < 0 or Q > 1) = 1: Floating point range error. Reference boost/math/special_functions
