Functions

poisson_P

This function computes the cumulative distribution functions P(k), Q(k) for the Poisson distribution with parameter mu.

poisson_Q

This function computes the cumulative distribution functions P(k), Q(k) for the Poisson distribution with parameter mu.

poisson_pdf

This function computes the probability p(k) of obtaining k from a Poisson distribution with mean mu, using the formula given above.
