Utilities for preparing Stan inputs and processing Stan outputs
Project description
StanIO
A set of Python functions for data-wrangling in the formats used by the Stan probabalistic programming language.
It is primarily developed for use in cmdstanpy.
Features
- Writing Python dictionaries to Stan-compatible JSON (with optional support for using
ujson
for faster serialization) - Basic reading of StanCSV files into numpy arrays
- Parameter extraction from numpy arrays based on StanCSV headers
- e.g., if you have a
matrix[2,3] x
in a Stan program, extractingx
will give you a(num_draws, 2, 3)
numpy array
- e.g., if you have a
