Sep 1, 2025September 2025: Delivered an observability enhancement in tfojo1/jheem_analyses by adding an informational print in rw_state_results.R to signal usage of urbanicity data from an external R script. This improves data provenance, debugging, and reproducibility for downstream analyses. The change is tracked in commit 61fb70b9c1f55e1bd93df652a162e05a3853ce1d and lays groundwork for future data-automation improvements.

May 1, 2025May 2025 performance summary for tfojo1/jheem_analyses: Delivered a configurable, state-level HIV prevalence analysis script (R) that computes total prevalence for a set of target states in 2021 and compares it to the national prevalence for the same year. The script loads a config file and defines the target states list to enable reproducible analyses and easy extension to additional states or years. Commit recorded: 4c592343684ca6e9c10f654a09e1679a605347b4 (state-level prevalence total).

Dec 1, 2024December 2024 monthly summary for tfojo1/jheem_analyses: Delivered calibration tooling enhancements and a new review workflow to improve model weighting, scenario analysis, and reproducibility. Implemented TOTAL.WEIGHT = 0.5 across all likelihoods and migrated calibration code from full.with.aids to full.with.aids2, enabling more balanced calibration outcomes. Introduced a calibration review script suite that sets up the JHEEM engine, runs simulations with adjusted parameters, and generates plots (diagnosed prevalence, new diagnoses, AIDS diagnoses) across key dimensions and time horizons. Completed repository maintenance by archiving legacy configurations to simplify future experiments. No critical bugs fixed this month; primary focus was on robust calibration tooling, reproducibility, and maintainability.
