I am trying to implement a program which calculates the mean and moment by using the Boost library’s accumulator. Here is the code:
#include <iostream>
#include <boost/accumulators/accumulators.hpp>
#include <boost/accumulators/statistics/mean.hpp>
#include <boost/accumulators/statistics/moment.hpp>
using namespace boost::accumulators;
int main()
{
accumulator_set<double,stats<tag::mean,tag::moment<2> > >acc;
//push in some data
acc(1.2);
acc(2.3);
acc(3.4);
acc(4.5);
std::cout<<"Mean : "<<mean(acc)<<std::endl;
std::cout<<"moment : "<<accumulators::moment<2>(acc)<<std::endl;
return 0;
}
But I get a long error list (listed below). Instead of accumulators I have tried boost::accumulator because at the line where I use the accumulator program it shows me a red line and after use of boost::accumulator a red line was hidden but errors are the same.
How can I fix this problem?
