Unused parameter warning in mean.hpp

1

``` In file included from ../../boost/accumulators/statistics/mean.hpp:18: ../../boost/accumulators/statistics/count.hpp:48:57: error: unused parameter 'file_version' [-Werror,-Wunused-parameter] void serialize(Archive & ar, const unsigned int file_version) ``` You could run the CI tests with -Werror to...

Some accumulators are addable: count, sum, mean, variance. The proposal is to support operator+ for these and for accumulator_set if all stored accumulators are addable.

Add prefetch to core

2

We are currently implementing a new algorithm in Boost.Histogram which is supposed to profit from cacheline prefetching. The prefetch instruction is a builtin, so we need code to get a...

For Boost.Histogram, I need a new type of container. I plan to implement a private version to keep histogram decoupled from Boost.Container, but I wanted to propose this type of...

request: tuple_slice

I am manipulating function arguments in boost.histogram, which I pass around as `std::tuple`. I found that I need a `tuple_slice` function, something which strips off some elements from a tuple...

Boost.Hana implements [user-defined literals for compile-time numbers](https://www.boost.org/doc/libs/1_61_0/libs/hana/doc/html/structboost_1_1hana_1_1integral__constant.html#a1c078fd00db48686ca9e0aa17f47344e). These would be useful to have also in projects that solely use Boost.Mp11 for TMP.

Generate random 2d contingency table with given marginal totals

## Motivation Sometimes you have pairs of values x, y and you want to know whether y is independent of x or not. People sometimes compute the correlation of x...

aghast in C++?

2

A commonly requested feature for Boost.Histogram in C++ is to convert from and to ROOT histograms. In Python, we can do that already now with aghast, but not from C++....

Adding boost-histogram to tutorial

Is it possible to add boost-histogram to the tutorial on how to use Aghast? People are asking me how to convert ROOT histograms to boost-histograms and it would be nice...

Tests are missing for histograms

Histograms are completely untested, and the current implementation of TH1 methods has bugs.
