BetaRegularized

• Mathematical function, suitable for both symbolic and numerical manipulation.

• For non-singular cases, .

• BetaRegularized[z₀, z₁, a, b] gives the generalized regularized incomplete beta function defined in non-singular cases as Beta[z₀, z₁, a, b]/Beta[a, b].

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

• For certain special arguments, BetaRegularized automatically evaluates to exact values.

• BetaRegularized can be evaluated to arbitrary numerical precision.

• BetaRegularized automatically threads over lists.
