This paper describes an algorithm and provides a Matlab implementation for calculating the noncentral beta distribution function. Through a series of numerical tests, we demonstrate that the algorithm is accurate and efficient across a wide range of parameters.}, organization = {Open Access funding provided thanks to the CRUE-CSIC agreement with Springer Nature.
