Calculate the CDF of Poisson distribution with Boost C + + Library

The cumulative distribution function (CDF) of Poisson distribution can be easily calculated by R function Ppois () or octave /matlab function Poisspdf (). However, it isn't a easy thing to deal with statistics with C + + from scratch.

Today I found a very powerful C + + mathematical library (actually not limited to math), boost. Unfortunately, it is hard to figure out the API of the ' boost library from the ' Code if you are not familiar with generalization Programming (just like me). Besides, there is no useful ' Hello World ' examples on the Internet to show the Boost library handling statistics (examples on webpage C + + statistical distributions in Boost are a bit complicated and the header files are not included).

Therefore, I made up following example to show how to get the CDF of Poisson distribution with boost C + + library:

#include <boost/math/distributions/poisson.hpp>
#include <iostream>

using namespace std;
using namespace Boost::math;

int main ()
{
        poisson_distribution<> P (2.9);
        cout<< "Cdf:ppois (1,2.9) =" <<CDF (p,1) <<endl;

        return 0;
}
