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.
