umontreal.iro.lecuyer.randvar.LognormalGen
public class LognormalGen
This class implements methods for generating random variates from the lognormal distribution. Its density is
No local copy of the parameters μ and σ is maintained in this class. The (non-static) nextDouble method simply calls inverseF on the lognormal distribution object. One can also generate a lognormal random variate X via
