spey - v0.2.2

This release includes improvement in the $\chi^2$-test module, allowing the user to set signal yields to negative values. Previous versions did this depending on the requested region of the two-sided limits.

Additionally, NumPy v2 can now be used with Spey. In previous versions, this was constrained by the limitations of the Autograd package.

  • [feat] Allow control over negative signal yields in https://github.com/SpeysideHEP/spey/pull/50

spey - v0.2.1

This release introduces specific control mechanisms for invalid covariance matrices, such as ones with infinite determinants.

What's Changed

  • [bug] Issue with infinite determinant in https://github.com/SpeysideHEP/spey/pull/47

spey - v0.2.0

This release introduces the ability to perform two-sided statistical tests for SMEFT studies, enabling users to constrain the parameter of interest (POI) in both cases:  $\mu > \hat\mu$ and $\hat\mu > \mu$.

Next Steps: * The transition from autograd to JAX will take place in the v0.2.x series, unlocking GPU acceleration and improved integration with machine learning frameworks.

Let me know if you’d like any further refinements!

What's Changed

  • Add pre-commit in https://github.com/SpeysideHEP/spey/pull/44
  • [feat] Implementation of two-sided tests with lower and upper bounds on the POI in https://github.com/SpeysideHEP/spey/pull/45

spey - v0.1.11

This update addresses a bug in the statistics combination module for a specific use case. When searching for the optimal value of $\hat{\mu}$ in the combined likelihood for the optimiser, the computation for $\sigma_\mu$ may crash if the Hessian matrix is non-invertible. In cases where the Hessian is non-invertible, the search for optimal $\hat{\mu}$ is halted, deferring to the optimizer to complete the estimation.

Thanks to @joes-git for pointing this out.

spey - 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.

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.
