Implements Pascal random variate generators by the convolution method (see [114] ).
The method generates \(n\) geometric variates with probability \(p\) and adds them up.
The algorithm is slow if \(n\) is large.

| int umontreal.ssj.randvar.PascalConvolutionGen.nextInt | ( | ) |
Generates a random number (an integer) from the discrete distribution contained in this object.
By default, this method uses inversion by calling the inverseF method of the distribution object. Alternative generating methods are provided in subclasses.
