ADNI data is made available to researchers around the world. As such, there are many active research projects accessing and applying the shared ADNI data. To further encourage Alzheimer’s disease research collaboration, and to help prevent duplicate efforts, the list below shows the specific research focus of the active ADNI investigations. This information is requested annually as a requirement for data access.
|Principal Investigator's Name:||Alden Gross|
|Institution:||Harvard Medical School|
|Proposed Analysis:||I am part of the Friday Harbor Psychometrics workshop, and plan to be in a workgroup focusing on the longitudinal modeling of neuropsychological performance and neuroimaging data using frequentist techniques with continuous and categorical latent variables and random effects. We will apply modern psychometric modeling approaches to ADNI neuropsychological data to learn how item response theory models and their generalizations to discontinuous and continuous data (of the kind seen in neuropsychological batteries) can be nested in models of change over time or age. Frequentist model checking and diagnostics will be addressed in this hands-on workshop.|
