These resources present a training course on longitudinal data analysis (LDA) using the Traumatic Brain Injury Model
Systems National Database (TBIMS NDB). The course builds upon simple linear regression, progressively introducing
mixed-effects regression models (MRMs) to analyze repeated measures over time. It emphasizes the advantages of MRMs,
such as handling incomplete data and modeling individual-level changes. The TBIMS NDB, a large longitudinal study on
TBI, serves as the primary data source for examples and demonstrations. The course materials, including data and code,
are available online.
