ArviZ

ArviZ (/ˈɑːrvɪz/ AR-vees) is a Python package for exploratory analysis of Bayesian models [1][2] it offers data structures for manipulating data that it is common in Bayesian analysis, like numerical samples from the posterior, prior predictive and posterior predictive distributions as well as observed data. Additionally, many numerical/visual diagnostics and plots are available. The ArviZ name is derived from reading "rvs" (the short form of random variates) as a word instead of spelling it and also using the particle "viz" usually used to abbreviate visualization.

ArviZ is an open source project, developed by the community and is an affiliated project of NumFocus.[3] and it has been used to help interpret inference problems in several scientific domains, including astronomy[4], neuroscience [5], physics[6] and statistics.[7][8]


Library features
  • InferenceData object for Bayesian data manipulation. This object is based on xarray
  • Plots using two alternative backends matplotlib or bokeh
  • Numerical summaries and diagnostics for MCMC methods.
  • Integration with established probabilistic programming languages including; PyStan (the Python interface of Stan), PyMC [9], Edward[10] Pyro [11], and easily integrated with novel or bespoke Bayesian analyses. ArviZ is also available in Julia, using the ArviZ.jl interface
gollark: I mean, if it is randomly undefined I *would* like to know why.
gollark: That works fine.
gollark: I added `console.log` in it and apparently `ctx` is `[undefined, "the value of id", undefined]`.
gollark: I'm using esbuild and esbuild-svelte.
gollark: (`result` is an object)
