Jelmer Pastoor contributed to the t-kist/Bayesian-Statistics-for-Astrophysics-2024 repository by developing an autocorrelation-based workflow for Markov Chain Monte Carlo (MCMC) burn-in and posterior sampling, enhancing the reliability of Bayesian inference in astrophysical data analysis. Using Python and Jupyter Notebook, Jelmer implemented utilities for autocorrelation calculation and automated burn-in estimation, reducing manual intervention and improving convergence diagnostics. Additionally, Jelmer addressed documentation quality by correcting Markdown formatting in the Metropolis-Hastings lecture notes, ensuring accurate mathematical rendering and improved readability. The work demonstrated technical depth in statistical analysis and technical writing, supporting both robust computation and clear educational content.
December 2024: Delivered autocorrelation-based MCMC burn-in and posterior sampling functionality for Bayesian inference in astrophysical datasets (t-kist/Bayesian-Statistics-for-Astrophysics-2024). Added an autocorrelation calculation utility, automated burn-in time estimation, and a post-burn-in posterior sampling workflow, with a practical demonstration in the repository. The work is captured in commit 4f1bc5fb9cbdfd9f8dd31d5f02bbb5c94f595be6 titled "Autocorrelation is added". This enhances convergence diagnostics, reduces manual guesswork, and improves reliability of posterior inferences for astrophysical analyses.

November 2024 focused on improving the quality and reliability of educational content in the Bayesian Statistics for Astrophysics course. Delivered a targeted bug fix to the Metropolis-Hastings notebook that corrected Markdown formatting, removed extraneous backslashes, and ensured mathematical formulas render accurately. These changes enhance student comprehension, reduce confusion, and improve maintainability of lecture notes for future updates.
