This article develops some general theory for testing the rank of a matrix. Applications include tests of interaction in two-factor experiments that are more powerful than the usual F test for certain ...

Parametric interval linear systems are a class of mathematical models in which the coefficients of the matrix and the right‐hand side vector depend linearly on one or more parameters constrained ...

An approximation to the marginal likelihood of the ranks of a set of observations is used to analyse data. The observations, after some arbitrary monotone transformation, are assumed to be ...
