WebThis module serves as an introduction to the PyMC3 framework for probabilistic programming. It introduces some of the concepts related to modeling and the PyMC3 syntax. The visualization library ArViz, that is integrated into PyMC3, will also be introduced. WebStatistics and diagnostics are delegated to the ArviZ. library, a general purpose library for “exploratory analysis of Bayesian models”. Functions from the arviz.statsmodule are available through pymc3.or pymc3.stats., but for their API documentation please refer to the ArviZ documentation.
