accumulator extended quantil value
Hello, I have got created an extended_p_square_quantile into an accumulator, with 3 quantils (0.25, 0.5, 0.75) as a boost::array. How can I get access to the quantil values of the accumulator? For the variance I use accumulator::variance(myacc), but a call with quantil(myacc, 0.5) does not work. Thanks Phil

I use for reading the quantil value namespace bac = boost::accumulator bac::quantil( myvar, bac::quantile_probability = 0.5) but the value is very different of the median. If I run median & 0.5 quantil, the median results eg 930.67932 and the quantil value is 0. So I can not explain this large difference. My accumulator uses median & 0.5 quantil, so the accumulator is used equal data. Can anybody help me please to fix this problem? Phil

I use for reading the quantil value
namespace bac = boost::accumulator bac::quantil( myvar, bac::quantile_probability = 0.5)
It's spelled "quantile".

Maybe Matthias Troyer will chime in. -- Eric Niebler Boost.org http://www.boost.org

Yes, it is a typo error during the fast writing

At the moment I can not create a working solution, so I hope for some ideas :-) Phil
