摘要：Batting average is one of the principle performance measures for an individual baseball player. It is natural to statistically model this as a bionomial variable proportion, with a given (observed) number of qualifying attempts (called at-bats), an observed number of successes (hits) distributed according to the binomial distribution, and with a true (but unknown) value of pi that represents the player's latent ability. This is a common data structure in many statistical applications; and so t...

摘要：Diffusion tensor imaging (DTI) is a novel modality of magnetic resonance imaging that allows noninvasive mapping, of the brain's white matter. A particular map derived from DTI measurements is a map of water principal diffusion directions, which are proxies for neural fiber directions. We consider a study in which diffusion direction maps were acquired for two groups of subjects. The objective of the analysis is to find regions of the brain in which the corresponding diffusion directions diffe...
