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

DetailsDetails

  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • For nonsingular cases, .
  • BetaRegularized[z0,z1,a,b] gives the generalized regularized incomplete beta function defined in nonsingular 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.
