FilledSmallSquareBetaRegularized[z, a, b] gives the regularized incomplete beta function .

FilledSmallSquare Mathematical function (see Section A.3.10).

FilledSmallSquare For non-singular cases, .

FilledSmallSquareBetaRegularized[, , a, b] gives the generalized regularized incomplete beta function defined in non-singular cases as Beta[, , a, b]/Beta[a, b].

FilledSmallSquare Note that the arguments in BetaRegularized are arranged differently from those in GammaRegularized.
