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). Our repositories contain code and tools to help longitudinal and cross-cohort research.

Cross-cohort data harmonisation code:

• Fertility Histories
• Smoking
• Asthma

Code for single cohorts:

• Time use data in MCS

Genetic analysis tools and polygenic scoring methods:

• CLS Polygenic Index Repository - Tools and scripts for calculating polygenic scores in longitudinal studies

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. Note also that the languages used differ by repository (e.g., Stata, R).

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
