Block circular symmetry in multilevel models

Liang, Yuli; von Rosen, Tatjana; Von Rosen, Dietrich


Models that describe symmetries present in the error structure of observations have been widely used in different applications, with early examples from psychometric and medical research. The aim of this article is to study a multilevel model with a covariance structure that is block circular symmetric. Useful results are obtained for the spectra of these structured matrices.
