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. 

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
