Separability tests for high-dimensional, low-sample size multivariate repeated measures data

Simpson, Sean L.; Edwards, Lloyd J.; Styner, Martin A.; … - In: Journal of Applied Statistics 41 (2014) 11, pp. 2450-2461

Longitudinal imaging studies have moved to the forefront of medical research due to their ability to characterize spatio-temporal features of biological structures across the lifespan. Valid inference in longitudinal imaging requires enough flexibility of the covariance model to allow reasonable...
