Takeaways:
- Zero Sum constraints allow for better sampling and estimation in hierarchical models.
- Understanding the difference between population and sample means is crucial.
- A library for zero-sum normal effects would be beneficial.
- Practical solutions can yield decent predictions even with limitations.
- Cholesky parameterization can be adapted for positive correlation matrices.
- Understanding the geometry of sampling spaces is crucial.
- The relationship between eigenvalues and sampling is complex.
- Collaboration and sharing knowledge enhance research outcomes.
- Innovative approaches can simplify complex statistical problems.
