Hello,

I would like to create a box plot and use the static calls of the boost. Median / average etc works well, but I need also the 25% & 75% quantil of my data, I'm using a
boost::accumulators::accumulator_set for calculating statistical data. Can I / How can I use this for the quantil calculation or should I do this myself?

Thanks

Phil

Hi,

Have you tried p_square_quantile from boost::accumulator?

http://www.boost.org/doc/libs/1_53_0/doc/html/accumulators/user_s_guide.html#accumulators.user_s_guide.the_statistical_accumulators_library.p_square_quantile

It uses a well-known algorithm to incrementally compute quantile estimation.

Best.
