Specific upgrades for the latest release can be found here.

New features since the last release#

The exclusion limit calculator has been extended to include p-value computation from chi-square. (#17)
\(\chi^2\) function has been extended to compute background + signal vs background only model. (#17)
A Poisson-based likelihood constructor without uncertainties has been added (Request by Veronica Sanz for EFT studies). (#22)

Backend inspection has been added for the models that act like intermediate functions. (#15)
Backend inspection has been converted to inheritance property via ConverterBase. (#17)
During POI upper limit computation, sigma_mu will be computed from Hessian, if available before approximating through \(q_{\mu,A}\). #25
Update clarification on text-based keyword arguments. (#30)
Adding logging across the software and implementing tools to silence them. (#32)
Spey will automatically look for updates during initiation. (#32)
Utilities to retrieve BibTeX information for third-party plug-ins. (#32)
Add math utilities for users to extract gradient and hessian of negative log-likelihood (#31)
Improve gradient execution for default_pdf. (#31)
Add more tests for code coverage. (#33)

In accordance with the latest updates, UnCorrStatisticsCombiner has been updated with a chi-square computer. See issue #19. (#20)
Execution error fix during likelihood computation for models with single nuisance parameter. (#22)
The numeric problem rising from == which has been updated to np.isclose see issue #23. (#25)
Typofix during computation of \(\sigma_\mu\). (#29)
Bug fix in signal uncertainty synthesizer (#34)
Signal uncertainties were causing a narrower \(\chi^2\) distribution due to the weight of the constraint term. (#38)
