Software, model documentation, and reproducible research archives.
π οΈ Active Software & R Packages
Our open-source codebase is the core of the STAPM platform. These packages are actively maintained, version-controlled, and assigned DOIs for academic citation.
smktrans
Estimating smoking state transition probabilities A tool for estimating transition probabilities from cross-sectional survey data. The documentation site includes reports that allow you to browse and download the estimates.
hseclean
Health Survey for England Wrangling Automated data cleaning and processing pipeline for the Health Survey for England. Standardizes variable names and categories across survey years.
tobalcepi
Epidemiological Calculation Engine Functions for computing Relative Risks (RR) and Population Attributable Fractions (PAF) for tobacco and alcohol-related harms.
mort.tools
Mortality Data Processing Tools for processing mortality microdata from England, Wales, and Scotland. Currently hosted as an OSF archive.
π Publication Code Archive
To ensure the reproducibility of our research, we maintain a dedicated repository for code snapshots linked to specific peer-reviewed publications.
