MRPWorkflow-method-pp_check

pp_check

The <code>$pp_check()</code> method creates posterior predictive check plots
to assess model fit by comparing observed data to replicated data from
the posterior predictive distribution. Check out the
<a href="https://mrp-interface.github.io/shinymrp/articles/example#pp_check">More examples of R6 classes</a>
vignette for usage examples.

Dual interfaces, graphical and programmatic, designed for
intuitive applications of Multilevel Regression and Poststratification (MRP).
Users can apply the method to a variety of datasets, from electronic health records
to sample survey data, through an end-to-end Bayesian data analysis workflow.
The package provides robust tools for data cleaning, exploratory analysis,
flexible model building, and insightful result visualization. For more details, see
