What’s new#



Version 0.8.1#

  • Add support for Python 3.12, drop support for Python 3.8

  • Improved support for zfit 0.20+

Thanks to @MoritzNeuberger for finding and proposing a hypothesis test fix.

Version 0.7.0#

  • Add support for Python 3.11, drop support for Python 3.7

Version 0.6.1#

  • fix toy generation with constraints

Version 0.6.0#

  • Upgrade to Python 3.10 and zfit >= 0.10.0

  • Enhanced speed toy limit calculation

  • Add multidimensionl PDF support

  • Add support for binned data and models

Version 0.5.0#

  • Upgrade to Python 3.9 and drop support for 3.6

Version 0.4.0#

  • loss: upgrade API to use create_new to make sure that the losses are comparable. Compatible with zfit 0.6.4+

Version 0.3.1#

  • sPlot: Increase the tolerance of the sanity check from 1e-3 to 5e-2, if above the tolerance a ModelNotFittedToData exception is raised. In addition if the the check is above the 5e-3 tolerance a warning message is printed.

Version 0.3.0#

  • New documentation style

  • hepstats can now do hypothesis tests, and compute upper limits and confidence intervals for counting analysis

  • Progess bars are used to see the progression of the generation of the toys

Version 0.2.5#

  • ConfidenceInterval can compute Feldman and Cousin intervals with boundaries (i.e qtilde=True)

  • AsymptoticCalculator asymov weights are now scaled to the number of entries in dataset from loss function if the loss is not extended

  • hepstats.hypotests can now be used even if there is no nuisances. The pll function in utils/fit/diverse.py had to be modified such that if there are no nuisances, the pll function returns the value of the loss function.

  • add notebooks demos for FC intervals with the FrequentistCalculator and AsymptoticCalculator.

  • add warnings when multiple roots are found in ConfidenceInterval

  • move toys .yml files from notebook to notebook/toys

Version 0.2.4#

  • Redesigned packaging system, GHA deployment.

  • expected_poi removed from BaseCalculator and AsymptoticCalculator

  • add type checks in the hypotests submodule

Version 0.2.3#

  • hepstats is now compatible with zfit > 0.5 api

  • expected intervals in upper limit are now calculated from the pvalues and not from the expected_poi function anymore.

Version 0.2.2#

  • Addition of the sPlot algorithm

Version 0.2.1#

  • Addition of the FrequentistCalculator to performs hypothesis test, upper limit and interval calculations with toys. Toys can be saved and loaded in / from yaml files using the methods:

    • to_yaml

    • from_yaml

Version 0.2.0#

  • New version for the new hepstats name of the package

Version 0.1.3#

  • Package name changed from scikit*stats to hepstats

Version 0.1.2#

  • Additions of classes to compute upper limits and confidence intervals.

Version 0.1.1#

  • Release for Zenodo DOI

Version 0.1.0#

  • First release of scikit*stats

  • Addition of the modeling submodule with the Bayesian Blocks algorithm

  • Addition of the hypotests submodule
