%description
To improve estimation accuracy and stability in statistical modeling,
catalytic prior distributions are employed, integrating observed data with
synthetic data generated from a simpler model's predictive distribution.
This approach enhances model robustness, stability, and flexibility in
complex data scenarios. The catalytic prior distributions are introduced
by 'Huang et al.' (2020, <doi:10.1073/pnas.1920913117>), Li and Huang
(2023, <doi:10.48550/arXiv.2312.01411>).
