title = "A fundamental partition in models with commutative orthogonal block structure",

abstract = "Models with commutative orthogonal block structure, COBS, constitute an interesting class of models with orthogonal block structure, OBS, in which the orthogonal projection matrix on the space ω spanned by the mean vectors commute with the known pairwise orthogonal projection matrices Q 1,..., Qm that figure in the expression of the variance-covariance matrix V = ∑j=1m γjQj of the model. We discuss the importance of the orthogonal partition Y = YΩ+YΩ⊥ where Y, Yω and Yω⊥ are the observation vectors and its orthogonal projection on ω and ω⊥, the orthogonal complement on parameters estimation.",
