I have a couple Qns about boost accumulators in 1_37_0 -

1) Central moments ? -

There are accumulators for simple kth moments -
boost/accumulators/statistics/moment.hpp

Are central kth moments [relative to the mean] there somewhere?

Obviously you can construct one from the other with a weighted sum of the k
moments on the same data.

2) Slow build ! -

It is a bit slow to compile code using eg. moment<6> accumulators..
It takes around 12 seconds on my machine to build sample code with
'moment<12>'

exponential recursive template evaluation??

I'm using gcc 4.2.4

cheers,

gord.
