Welcome to the GitHub organization for the Centre for Longitudinal Studies (CLS) at UCL.
This contains code repositories for the Centre for Longitudinal Studies (CLS), supporting research across the UK's major longitudinal cohort studies. Our repositories contain analysis code, data harmonisation tools, and research outputs that advance longitudinal research.
Cross-cohort data harmonisation and comparative analysis tools, for example:
- Fertility Histories in Four UK Cohort Studies - Harmonised fertility data across major UK cohorts
- Smoking in the Cohorts - Standardised smoking behaviour measures across studies
Genetic analysis tools and polygenic scoring methods:
- CLS Polygenic Index Repository - Tools and scripts for calculating polygenic scores in longitudinal studies (forthcoming Q3-4 2025)
Tools and resources for longitudinal data management:
- See CLS Data Management Resources - code for common data management tasks
Please note that repositories in this organization contain work in progress code. While we strive for quality and documentation, some projects may be in active development stages.
We welcome user feedback and contributions! You can:
- Contact the authors directly (see individual repository contacts or email clsdata@ucl.ac.uk)
- Open an issue on the relevant GitHub repository
- Submit pull requests for improvements or bug fixes
