Tofu is a Python library for generating synthetic UK Biobank data. The UK Biobank is a large open-access prospective research cohort study of 500,000 middle-aged participants recruited in England, Scotland and Wales. The study has collected and continues to collect extensive phenotypic and genotypic detail about its participants, including data from questionnaires, physical measures, sample assays, accelerometry, multimodal imaging, genome-wide genotyping and longitudinal follow-up for a wide range of health-related outcomes. Tofu will generate synthetic data which conforms to the structure of the baseline data UK Biobank sends researchers by generating random values. For categorical variables (single or multiple choices), a random value will be picked from the UK Biobank data dictionary for that field. For continuous variables, a random value will be generated based on the distribution of values reported for that field on the UK Biobank showcase.
Features
- For categorical variables (single or multiple choices), a random value will be picked from the UK Biobank data dictionary for that field
- For continous variables, a random value will be generated based on the distribution of values reported for that field on the UK Biobank showcase
- For date and date/time fields, a random date will be generated
- For all other fields, such as polymorphic fields, no data will be generated
- The lookups directory contains lookups downloaded from the UK Biobank showcase
- Data conform to the structure and schema of the baseline file but are otherwise nonsensical: no checks have been implemented across fields
