Description

Notebook title:GLM: Hierarchical Linear Regression Notebook url: source link, website link

Issue description

There are many, many divergences in the sample of the main, hierarchical model. There also appear to be images missing under "The Models" section. Not sure what these are supposed to be.

Proposed solution

I suspect the sampling could be fixed by re-running and/or setting the random seed for stability. Not sure what the images were (at one time).

Contributor guide

Research direction
Re run the notebook with a fixed random seed to check if divergences persist. Also verify all image references and ensure image files are present in the repository.
