Multivariate brain-wide associated studies can be replicable with substantially smaller sample sizes
Since the development of functional magnetic resonance imaging in the 1990s, the reliance on neuroimaging has skyrocketed as researchers investigate how fMRI data from the brain at rest, and ...
Some existing nonparametric two-sample tests for equality of multivariate distributions perform unsatisfactorily when the two sample sizes are unbalanced. In particular, the power of these tests tends ...
Asymptotic expansions are derived for the densities of multivariate M-estimates. The expansion is based on a saddlepoint technique and yields good accuracy in the tails for small sample sizes.
