validate_positive

This function checks whether a parameter value is positive (or non-negative if <code>incl_0</code> is set to <code>TRUE</code>).
It can handle both single numeric values and vectors, and it raises an error with an informative
message if the validation fails.

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>).
