arviz.InferenceData

class arviz.InferenceData(attrs=None, **kwargs)

Container for inference data storage using xarray.

For a detailed introduction to InferenceData objects and their usage, see Introduction to xarray, InferenceData, and netCDF for ArviZ. This page provides help and documentation on InferenceData methods and their low level implementation.
