Detailed Description

Implements methods for generating random variates from the lognormal distribution using an arbitrary normal random variate generator.

The (non-static) nextDouble method calls the nextDouble method of the normal generator and takes the exponential of the result.

Constructor & Destructor Documentation

umontreal.ssj.randvar.LognormalSpecialGen.LognormalSpecialGen ( NormalGen g )

Create a lognormal random variate generator using the normal generator g and with the same parameters.

Definition at line 45 of file LognormalSpecialGen.java.

double umontreal.ssj.randvar.LognormalSpecialGen.nextDouble ( )

Generates a random number from the continuous distribution contained in this object.

By default, this method uses inversion by calling the umontreal.ssj.probdist.ContinuousDistribution.inverseF method of the distribution object. Alternative generating methods are provided in subclasses.
