Abstract

Explicit formulas are given to recursively generate the moments of the mean M for Dubins–Freedman random distribution functions with arbitrary base measure μ. Using a standard inversion formula for moments of a distribution on the unit interval, the distribution of M is approximated for several natural choices of μ. The support of the mean is also considered. It is shown that the support of M is connected whenever μ is concentrated on the vertical bisector of the unit square S, but may have arbitrarily many gaps otherwise.
