Poisson Distribution

This class produces Poisson distribution with a user-provided lambda. Optionally, a random number generator can also be provided for sampling. If a random number generator is not provided, Mersenne will be used.

Constructor​

PoissonDistribution(double mn);
PoissonDistribution(double mn, SST::RNG::Random* baseRNG);

Parameters​

  • mn (double) The lambda for the distribution.
  • baseRNG (SST::RNG::Random*) A random number generator for sampling the distribution

getNextDouble​

double getNextDouble();

Return the next double in the distribution.

Parameters​

  • returns (double) The next double in the distribution

getLambda​

double getLambda();

Return the lambda of the distribution.

Parameters​

  • returns (double) The lambda of the distribution

Example​

SST::RNG::PoissonDistribution* dist = new SST::RNG::PoissonDistribution(5.0);

double next;
next = dist->getNextDouble();
