CmdStanPy

CmdStanPy is a lightweight interface to Stan for Python users which provides the necessary objects and functions to compile a Stan program and run Stan's samplers.

Goals

  • Clean interface to Stan services so that CmdStanPy can keep up with Stan releases.

  • Provides complete control - all sampler arguments have corresponding named argument for CmdStanPy sampler function.

  • Easy to install,

    • minimal Python library dependencies: numpy, pandas
    • Python code doesn't interface directly with c++, only calls compiled executables

  • Modular - CmdStanPy produces a sample from the posterior, downstream modules do the analysis.
