### Describe the bug
We are trying to fit some synthesized data with 1 normalization, 1 signal, and 2 background templates. All templates are 3D templates.
Our ba…

## Description
One of the most widely used binned models within ATLAS (almost all SUSY searches) is HistFactory, which is a declarative specification of a binned likelihood. We re-implemented the H…

it would be great to have some ability to achieve the same things than what ROOT's `HistFactory` or pure-python's `hf` do:

`HistFactory` deals with templates that describe the distribution of a sample when varying a single parameter (corresponding to a systematic uncertainty). For two parameters `(a, b)`, usually four tem…

In the HistFactory definition, following the [original document](https://cds.cern.ch/record/1456844/files/CERN-OPEN-2012-016.pdf), there is the following table of "modifiers":

Integrate the work started by @lukasheinrich on allowing ROOT and HistFactory input formats into the hepdata-converter package.

Currently most of the heavy computational lifting is done by Numpy.
Conversion of functions and data structures into TensorFlow and PyTorch formats can (and should) be done.
Now that basic com…
