Ibetaia() Function Ibetaia ( B As  Double, X As  Double, P As  Double, Optional Info As  Long  ) Normalized incomplete beta function Ix(a, b) inverse for a Purpose This routine returns a value a such that p = Ix(a, b), where p is the specified value of the normalized incomplete beta function. Returns Double Value of a. Parameters [in] B Argument b. (B > 0) [in] X Argument x. (0 < X < 1) [in] P Specified value of normalized incomplete beta function. (0 <= P <= 1) [out] Info (Optional) = 0: Successful exit. = -1: The argument B had an illegal value. (B <= 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
