Initialize method for continuous one-dimensional distribution. User must provide a distribution object (which is copied inside) and a string for a method. For the list of available method for 1D cont. distribution see the UnuRan doc. A re-initialization is needed whenever distribution parameters have been changed.

Initialize method for continuous empirical distribution. User must provide a distribution object (which is copied inside) and a string for a method. The distribution object can represent binned (only 1D) or unbinned (1D or multi-dim) data The method for the unbinned empirical distribution are based on the kernel smoothing, see UnuRan doc A re-initialization is needed whenever distribution parameters have been changed.

Initialize method for the Poisson distribution Used to generate poisson numbers for a constant parameter mu of the Poisson distribution. Use after the method TUnuran::SampleDiscr to generate the numbers. The flag reinit perform a fast re-initialization when only the distribution parameters are changed in the subsequent calls. If the same TUnuran object is used to generate with other distributions it cannot be used.
