Andrew E Gelman The Data Science Institute At Columbia University The document outlines andrew gelman's data science workflow, which includes fitting models to data in stan, checking model convergence, comparing different models, and updating models based on new insights. We consider several aspects of data analysis that are underemphasized in most presentations of statistical theory and practice. we illustrate some of these with a simple example of bayesian workflow and conclude by emphasizing shared aspects of bayesian and non bayesian data analysis workflows. The bayesian workflow is illustrated in this paper by gelman et al., and we will illustrate in this post and in the following ones how to implement it in pymc. we will assume that you properly collected some data, and you want to analyze it. All of these aspects can be understood as part of a tangled workflow of applied bayesian statistics. beyond inference, the workflow also includes iterative model building, model checking, validation and troubleshooting of computational problems, model understanding, and model comparison.

In this tutorial, we demonstrate how to formulate, fit, and diagnose a compartmental transmission model in stan, first with a simple susceptible‐infected‐recovered model, then with a more elaborate. We illustrate this thesis by following a single real example, estimating the global concentration of a certain type of air pollution, through all of the phases of statistical workflow: model comparison via tools such as cross validation.

The bayesian approach to data analysis provides a powerful way to handle uncertainty in all observations, model parameters, and model structure using probability theory, and this work reviews all aspects of workflow in the context of several examples.
