Diabetes Mediation Teaching Dataset

A health-related teaching dataset prepared from synthetic diabetes data. It is designed for the practical question: could part of the obesity and diabetes relationship operate through plasma glucose, after adjustment for basic clinical covariates?

Usage

Details

This dataset is intended for practice and teaching. Mediation estimates from observational data should be interpreted causally only when the temporal ordering and no-unmeasured-confounding assumptions are justified by study design, DAGs, and subject-matter knowledge.
