Over a three-month period, contributed to the stan-dev/math repository by enhancing the Wiener distribution’s numerical stability, readability, and error handling. Focused on refining core probability calculations, including CDF and log-CDF, and ensured compatibility with automatic differentiation. Leveraged C++ and numerical analysis skills to implement robust input validation, address edge-case failures, and standardize code formatting for maintainability. Introduced support for defective Wiener distributions, updating library integration and include directives to enable broader probabilistic modeling. The work improved reliability and consistency in statistical modeling workflows, reducing risk in production simulations and supporting more accurate risk and uncertainty evaluation across downstream analytics.
