oasis

This dataset consists of a longitudinal collection of 150 subjects aged 60 to 96. 
Each subject was scanned on two or more visits, separated by at least one year 
for a total of 373 imaging sessions. For each subject, 3 or 4 individual T1-weighted 
MRI scans obtained in single scan sessions are included.

datasets

Runs resampling-based tests jointly, e.g., sign-flip score tests from Hemerik et al., (2020) <doi:10.1111/rssb.12369>, to allow for multivariate testing, i.e., weak and strong control of the Familywise Error Rate or True Discovery Proportion.
