v0.1.9

This release extends the limitations on the requirements, especially for SciPy and Autograd.

Normal and multivariate normal distributions have been added as PDFs. This update is specifically for integration with Contur. Thanks to @jonbutterworth and @joes-git.

Notes for the next release: Due to some deprecated system packages, some issues have been observed when Spey is used in Python 3.12. These issues will be fixed in the next release.

Full Changelog: v0.1.6...v0.1.7

v0.1.6

This release enhances several aspects of the spey workflow:

• Users will be able to access the gradient and hessian functions of the statistical models.
• Enhance the logging structure of the package, including debugging tools.
• Gradient execution has been optimised for faster optimisation.
• Spey will be able to provide BibTeX information for third-party plug-ins through their arXiv number, DOI and Zenodo identifiers (if provided in plug-in metadata).

What's Changed

• Logging and BibTeX by @jackaraz in #32
• Optimise gradient execution by @jackaraz in #31
• logging, gradients, and BibTeX by @jackaraz in #33

Full Changelog: v0.1.5...v0.1.6

v0.1.5

This release updates a typo in the computation of $\sigma_\mu$, which causes the function to crash. Additionally, text-based types are changed to literals to improve the interpretability of the code.

What's Changed

• Update documentation in #27
• Update typing in #30
• Bugfix in $\sigma_\mu$ computation in #29

Full Changelog: v0.1.4...v0.1.5

v0.1.4

This version includes a minor update for numeric comparison during the computation.

What's Changed

• Numeric instability due to comparison with zero in #25
• Update documentation in #26

Full Changelog: v0.1.3...v0.1.4

v0.1.3

New Poisson likelihood without uncertainty implementation has been added (request by Veronica Sanz for EFT studies).

A full changelog can be found in the documentation.

What's Changed

• Exclusion limits from chi-square in #17
• Backend inspection in #15
• Align UnCorrStatisticsCombiner with recent updates in #20
• Docs in #21
• Poisson likelihood without uncertainty implementation in #22

Full Changelog: v0.1.0...v0.1.3

v0.1.2

This update fixes a minor bug in UnCorrStatisticsCombiner. The full changelog for v0.1 can be found in this link.

What's Changed

• Align UnCorrStatisticsCombiner with recent updates in #20

Full Changelog: v0.1.0...v0.1.2

v0.1.1

This release extends exclusion limit computation with $\chi^2$ based techniques for the likelihood constructions that can not generate samples and/or compute Asimov likelihood, e.g. some ML-based likelihoods.

The full changelog for this release can be found in this link.

What's Changed

• Exclusion limits from chi-square by @jackaraz in #17
• Backend inspection by @jackaraz in #15
