Some possible extra materials to cover this topic:

• A youtube video Introduction of the concepts and a simple example;
• Hamiltonian Monte Carlo for Hierarchical Models from M. J. Betancourt and Mark Girolami;
• A General Framework for the Parametrization of Hierarchical Models from Omiros Papaspiliopoulos, Gareth O. Roberts, and Martin Sköld;
• Efficient parametrisations for normal linear mixed models from Alan E. Gelfand, Sujit K. Sahu and Bradley P. Carlin.
