Module rgsl::randist::poisson

Functions

poisson	This function returns a random integer from the Poisson distribution with mean mu. The probability distribution for Poisson variates is,
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.
