v2.5.0

Octofitter v2.5.0

Diff since v2.4.0

• Fixes to @System and @planet macro scoping
• Improved error messages for some kinds of model mis-specifications
• New feature: load and save basic chains in Orbitize! HDF5 format.
• New feature: load posteriors and sample data directly from whereistheplanet.com
• New feature: compute point wise likelihoods and cross-validation scores via PSIS-LOO
• Tweak to Sine() prior for numerical issues (limits are now eps() instead of zero)
• UniformCircular() priors now have a less aggressive prior on the internal vector length
• Pigeons sampler now starts from a better location upon initialization
• Change: Enzyme is no longer loaded by default, and must be imported by the user. As a result, the package load time is much faster! The default :ForwardDiff autodial backend is unchanged

v2.4.0

Octofitter v2.4.0

Diff since v2.3.1

• Fixes to Enzyme forward-mode autodiff
• Experimental function for calculating pointwise likelihoods given a model and posterior chain
• Fix regression in corner plots

Octofitter v2.3.0

Diff since v2.2.0

• Automatically save the plot outputs of octocorner using the already-provided system name.

v2.2.0

Octofitter v2.2.0

Diff since v2.1.0

• Add helpers for using the theta parameter published in the octofitter paper
• Improve the corner plot output to always show the actual variable names, not just English descriptions. This can be overridden by passing a labels dict.
• Speed up initial pathfinder solve (first phase of octofit) by reducing optimizer relative tolerance to 1e-10
• Improve compile times for each new model fit with octofit_pigeons slightly

• Gaussian process fitting for stellar activity
• Fit interferometric observables (squared visibilities and closure phases)
• Automatically generate corner plots
• "quick fit" mode to quickly approximate the posterior
