A closedform approximation for the median of the beta distribution
Abstract
A simple closedform approximation for the median of the beta distribution Beta(a, b) is introduced: (a1/3)/(a+b2/3) for (a,b) both larger than 1 has a relative error of less than 4%, rapidly decreasing to zero as both shape parameters increase.
