## umontreal.iro.lecuyer.randvar
Class JohnsonSBGen

    java.lang.Object
      umontreal.iro.lecuyer.randvar.RandomVariateGen
          umontreal.iro.lecuyer.randvar.JohnsonSBGen

    public class JohnsonSBGen

extends RandomVariateGen

This class implements random variate generators for the Johnson SB distribution.

Constructor Summary
`JohnsonSBGen(RandomStream s, double gamma, double delta, double xi, double lambda)` Creates a JohnsonSB random variate generator.
`JohnsonSBGen(RandomStream s, JohnsonSBDist dist)` Creates a new generator for the JohnsonSB distribution `dist`, using stream `s`.

Method Summary
`double` | `getDelta()` Returns the δ associated with this object.
`double` | `getGamma()` Returns the γ associated with this object.
`double` | `getLambda()` Returns the λ associated with this object.
`double` | `getXi()` Returns the ξ associated with this object.
`static double` | `nextDouble(RandomStream s, double gamma, double delta, double xi, double lambda)` Uses inversion to generate a new JohnsonSB variate, using stream `s`.
