>             Project: Commons RNG
>          Issue Type: Improvement
>            Reporter: Gilles

> In relation to RNG-41, I propose to create a {{LogNormalSampler}} base class:
> {noformat}
> class LogNormalSampler {
>     protected LogNormalSampler(NormalizedGaussianSampler gaussian,
>                                double scale,
>                                double shape) {
>         // ...
>     }
> }
> {noformat}
> Derived (public) classes will differ by the algorithm used to generate normalized Gaussian deviates.
