The PyHEP talk about zfit and hepstats covers two main topics:

• first, we will talk about the newest features: the generalisation of the minimizer API and how to use it independently of zfit.
• then we will dive into zfit: from the basics to more advanced concepts including simultaneus fits, constraints and custom models.

To run the notebooks, either download them and install (inside a virtualenv or conda) with

pip install -r binder/requirements.txt

or they can be run in a binder instance

(or, if that fails or doesn't yet has the newest updates)
