## umontreal.iro.lecuyer.randvar
Class BetaSymmetricalGen

    java.lang.Object
      umontreal.iro.lecuyer.randvar.RandomVariateGen
          umontreal.iro.lecuyer.randvar.BetaGen
              umontreal.iro.lecuyer.randvar.BetaSymmetricalGen

Direct Known Subclasses:
  BetaSymmetricalBestGen, BetaSymmetricalPolarGen

    public class BetaSymmetricalGen

extends BetaGen

This class implements random variate generators with the symmetrical beta distribution with shape parameters α = β, over the interval (0, 1).

Constructor Summary
`BetaSymmetricalGen(RandomStream s, BetaSymmetricalDist dist)` Creates a new generator for the distribution `dist`, using stream `s`.
`BetaSymmetricalGen(RandomStream s, double alpha)` Creates a new symmetrical beta generator with parameters α = `alpha`, over the interval (0, 1), using stream `s`.

Method Summary
`static double` | `nextDouble(RandomStream s, double alpha)`
