hi,
 
I am a newbie in this forum. I just installed boost and want to solve some statistic problems. My system is Windows Vista and compiler is MSVC 6.0
 
At first I try to compile the "hello world" program in the boost::accumulators user guide page, but I got some compiler errors:
 
The program is  
 
#include <iostream>
#include <boost/accumulators/accumulators.hpp>
#include <boost/accumulators/statistics/stats.hpp>
#include <boost/accumulators/statistics/mean.hpp>
#include <boost/accumulators/statistics/moment.hpp>
using namespace boost::accumulators;
int main()
{
    // Define an accumulator set for calculating the mean and the
    // 2nd moment ...
    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);
    // Display the results ...
    std::cout << "Mean:   " << mean(acc) << std::endl;
    std::cout << "Moment: " << moment<2>(acc) << std::endl;
    return 0;
}
 
 
The error I get from compiler is
