This article describes how to go from a Hierarchical Bayes model output:

To a series of trace plots which show the main parameters change as the analysis progresses over the iterations for each chain:

## Requirements

- A document containing a Hierarchical Bayes output.

Please note these steps require a **Displayr **license.

## Method

- Select the Hierarchical Bayes output.
- From the
**object inspector**, click**Data > Diagnostics****> Trace Plots**.

A trace plot output will be generated:

The grey half-section on the plots indicates the warm-up iterations, which are excluded from the final results. The non-grey part is the final result. With more than a couple of cores, these plots can be hard to read. Beyond the warm-up stage, the range of each chain should overlap almost entirely with those of the other chains. If one chain appears higher or lower than the others, this would indicate a problem with the model and more iterations may be required.
