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

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...

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

Great thanks, I don't see this section. But another question: I have defined my accumulator like typedef boost::accumulators::accumulator_set > Accumulator; Within the example the quantil value is set in the Ctor of the accumulator. In my case I need two quantiles 0.25 & 0.75 so I need two p_square_quantile parts in my accu, so how I can add the two quantils and how I can set it to the values? Thanks Phil
