Detailed Description

This class permits one to create generators for empirical and quasi-empirical univariate distributions using UNURAN via its string interface.

The empirical data can be read from a file, from an array, or simply encoded into the generator specification string. When reading from a file or an array, the generator specification string must not contain a distribution specification string.

Constructor & Destructor Documentation

◆ UnuranEmpirical()

UnuranEmpirical ( RandomStream  s,
RandomStream  aux,
PiecewiseLinearEmpiricalDist  dist,
String  genStr 
)

Same as UnuranEmpirical(s, aux, genStr), but reading the observations from the empirical distribution dist.

The genStr argument must not contain a distribution part because the distribution will be generated from the input stream reader.
