✦ Synopsis

This paper describes an investigation into the relationship of closure, a baseline offset and mean centering to the interpretation of matrix rank. The equivalence of a certain type of closure to a constant baseline (i.e. a simple numerical offset which may vary between response channels but is constant over all samples) is demonstrated. A systematic approach to the interpretation of the rank of a matrix is given. KEY WORDS Closure Baseline Mean centering Rank Exploratory data analysis

Mandibular condyles translate back and forth during mouth closing and opening in primates and most other mammals. To account for the functional significance of this phenomenon, several hypotheses have been proposed. The sarcomere-length hypothesis holds that condylar translation provides a mechanica

Chen (1998) recently published the results of a study in which he recorded movement of the mandible during jaw opening in seven human subjects. From these data, Chen (1998) claims to have determined the location of the instantaneous center of rotation (ICR) of the human mandible using a two-dimensio
