Remarks

PoissonDistribution evaluates the Poisson probability density of a given set of data, xData. If parameters are not supplied, the Eval method fits the Poisson probability density function by first calculating theta, \theta. The Poisson probability density function is defined as:

f(x)= \frac{\theta^{x}e^{-\theta}}{x!}\,\,\mbox{,}\,\, x \ge 0\,\,\, \mbox{and}\,\,\, \theta > 0 \mbox{.}

The DataMining package class NaiveBayesClassifier uses PoissonDistribution as a method to train continuous data.
