Constructor Detail

Poisson

public Poisson(double alpha,
               double precision)

Constructs a Poisson object with a given average value without considering values for which the probability is less than a given precision

Parameters:

alpha - the value as a double of the average value in this poisson distibution

precision - the value as a double of the minimum probability which is of interest. Values less than this probablility will not be considered
