Detailed Description

Return the regularized Incomplete Beta Function $I_x(\alpha, \beta)$ as defined in the details section of pm_mathBeta.

Parameters

[in]	betaInc	: The output scalar (or array of the same shape as other array-like arguments) of the same type and kind as the input argument `x` containing the regularized Incomplete Beta Function.
[in]	x	: The input scalar (or array of the same shape as other array-like arguments) of, type `real` of kind any supported by the processor (e.g., RK, RK32, RK64, or RK128), containing the value at which the function must be computed.
[in]	alpha	: The input scalar (or array of the same shape as other array-like arguments) of the same type and kind as `x`.
[in]	beta	: The input scalar (or array of the same shape as other array-like arguments) of the same type and kind as `x`.
[in]	logFuncBeta	: The input scalar (or array of the same shape as other array-like arguments) of the same type and kind as `x`, representing the natural logarithm of the Beta Function as returned by getLogBeta(alpha, beta). Providing this argument can lead to significant runtime performance gains when the interface is called repeatedly for different `x` values but with identical `alpha` and `beta`.
[in]	signed	: The input scalar (or array of the same shape as other array-like arguments) of type `logical` of default kind LK. If `signed = .false.`, the input `x` must be in range `0 <= x <= 1` and the output `betaInc` will be the expected incomplete Beta function in range `0 <= betaInc <= 1`. If `signed = .true.`, then the following rules hold: If the condition `x < 0` holds, then the value `x = 1 - x < 0` will be used instead of `x`. If the output `betaInc` is near `1`, the output will be returned as `betaInc = betaInc - 1 < 0` instead of `betaInc`. Therefore, the user is expected to be aware of the convention and apply the necessary correction (addition by `1`) before using the output value. Specifying `signed = .true.` can lead to considerably more accurate calculations (by orders of magnitudes) for values of `x` and `betaInc` that are near `1`. The loss of precision near `1` occurs because of inadequate resolution of `real` number representations in digital computers near `1` which is orders of magnitude worse than the precision near `0`.
[in]	reltol	: The input scalar argument of the same type and kind as `betaInc`, representing the relative tolerance of integration in the definition of the Incomplete Beta function. If the relative accuracy of integration reaches a value below this threshold, the computation of the Incomplete Beta function is assumed to have converged. Specifying this argument will lead to brute-force numerical integration of the integrand of the Beta function to compute the integral. This approach can be useful when the continued-fraction representation of the Incomplete Beta Function fails to converge or is extremely costly or a bound on the numerical error is needed. Convergence failure or costly computations frequently occur for large values of `alpha` and `beta`. This argument can be set to any positive value significantly larger (e.g., $\times10000$) than `epsilon(real(0., kind(reltol))`. A good rule of thumb is to set `reltol = epsilon(real(0, kind(integral)))(2./3.)`. The integration result is generally orders of magnitude more precise than the specified `reltol`. (optional**. If missing, the continued-fraction representation of the Incomplete Beta function will be used to approximate the output.)
[out]	info	: The output scalar (or array of the same shape as other array-like arguments) of type `integer` of default kind IK. It is `0` if and only if the computation converges, otherwise, if the input argument `reltol` is missing, it is set to `1` to signal lack of convergence in the computation of the continued-fraction representation of the Incomplete Beta function. Convergence fails if `alpha` or `beta` are too large, in which case a brute-force integration method by specifying the input argument `reltol` might resolve it. if the input argument `reltol` is present, it is set to the non-zero `info` output of getQuadErr to signal lack of convergence in the computation of the integral. See the documentation of the output argument `info` of getQuadErr for possible output error codes and their meanings. The failure may be resolved by increasing the preset value of `MAX_ITER` in the implementation.

Warning: The conditions 0 <= x .and. x <= 1 must hold for the corresponding input arguments.
The conditions 0 < alpha .and. 0 < beta must hold for the corresponding input arguments.
These conditions are verified only if the library is built with the preprocessor macro CHECK_ENABLED=1.; The pure procedure(s) documented herein become impure when the ParaMonte library is compiled with preprocessor macro CHECK_ENABLED=1.
By default, these procedures are pure in release build and impure in debug and testing builds. The procedures of this generic interface are always impure when the input argument reltol is present.

Remarks: The procedures under discussion are elemental.
