Release 1.2.1

Fixed

• The PCE model is more accurate now that we're using the global max, and other modifications to make it more robust.

Release 1.2.0

Description

This release features new plots and some bug fixes.

New in this release

Sensitivity methods new score and rank plots

• One-at-a-time: calculates each parameters individual effect shows the magnitude in a score plot, and compares features in a rank plot. ibis.sensitivity.oat_score_plot and ibis.sensitivity.oat_rank_plot
• Sobol Indices: Calculates contributions of individual parameters and their interactions. The score plot shows first order or total order sensitivity indices. The rank plot compares them across the outputs. ibis.sensitivity.sobol_score_plot and ibis.sensitivity.sobol_rank_plot
• Morris method: Calculates elementary effects for each path through the parameter space, and calculates statistics mu* and sigma across all the trajectories to understand main effects and interactions. Score plot can show mu* and sigma, and rank plot just compares parameters based on mu* or sigma. ibis.sensitivity.morris_score_plot and ibis.sensitivity.morris_rank_plot
• These plots are also available as Kosh operators from ibis.kosh_operators.KoshSensitivityPlots

Bug fixes

• Updated some indexing and variable assignment methods to be compatible with numpy > 2.0
• Other fixes and updates to the testing suite

Release 1.1.1

1.1.1 Release

Description

This release includes some bug fixes and an update to the basic descriptions.

Improvements

• Updated descriptions for the main modules
• More explanation for discrepancy MCMC sampling

Bug fixes

• KoshMCMC function only has experimental data coming from a Kosh store.
• Fixed loop to allow for any number of quantity of interest and experiments in the KoshMCMC function.
• Allow for the case of only one quantity of interest (QOI) in the sensitivity plot, variance_network_plot, and rank plot.

Release 1.1.0

1.1.0 Release

This release introduces some new features

New in this release

Added Kosh operators to Ibis to be able to use
IBIS UQ and sensitivity methods with Kosh datasets.

• KoshMCMC
• KoshOneAtATimeEffects
• KoshSensitivityPlots

A sobol_indices function has been added to the sensitivity module. It's meant
to be used with the SobolIndexSampler in the Trata sampler module or similar.
