I try to create a complex accumulator. I would like to use an accumulator for a box plot with the whisker data ( http://en.wikipedia.org/wiki/Box_plot ).
This short example
#include <boost/accumulators/accumulators.hpp> #include <boost/accumulators/statistics/sum.hpp> #include <boost/accumulators/statistics/min.hpp> #include <boost/accumulators/statistics/max.hpp> #include <boost/accumulators/statistics/mean.hpp> #include <boost/accumulators/statistics/stats.hpp> #include <boost/accumulators/statistics/count.hpp> #include <boost/accumulators/statistics/median.hpp> #include <boost/accumulators/statistics/variance.hpp> #include <boost/accumulators/statistics/extended_p_square.hpp>
whoops, should be:
#include <boost/accumulators/statistics/extended_p_square_quantile.hpp>
#include <boost/array.hpp>
using namespace boost::accumulators;
typedef accumulator_set<double, stats< tag::count, tag::sum, tag::mean, tag::extended_p_square_quantile //*
accumulator_t;
int main() { boost::array<double,3> probs = {0.25, 0.50, 0.75}; accumulator_t acc(extended_p_square_probabilities = probs); }
compiles only, if I comment the //* line, but with the quantil tag the compiler creates this errors:
<snip>
The errors went away for me when I included the correct header. You might check the docs for the statistics you're using. The docs aren't great, but they at least tell you what headers to include.
http://www.boost.org/doc/libs/1_53_0/doc/html/accumulators/user_s_guide.html...
I can solve the problem :-P I have include these headers: #include <boost/array.hpp> #include <boost/accumulators/statistics.hpp> #include <boost/accumulators/accumulators.hpp> But my variable m_times is a std::map<std::string, accumulator> and I can not push the accumulator with m_times[<some string>] = Accumulator(...) I need the insert method of the map with a std::pair and for accessing the element does not work the m_times[<some string>](<a value>), I need the iterator of the map element and push the value to the accumulator with it->second(<a value>) Phil
