MathQuantileNoncentralBeta

Calculates the value of the inverse probability distribution function of noncentral beta distribution with the a, b and lambda parameters for the occurrence probability of a random variable probability. In case of error it returns NaN.

For the specified probability[] array of probability values, the function calculates the value of the inverse probability distribution function of noncentral beta distribution with the a, b and lambda parameters. In case of error it returns false. Analog of the qbeta() in R.
