A Fundamental Partition in Models with Commutative Orthogonal Block Structure

AIP Conference Proceedings, 2011
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 Q1,…, Qm that figure in the expression of the variance‐covariance ...

Orthogonal and Nonorthogonal Methods for Partitioning Regression Variance

American Educational Research Journal, 1971
Bottenberg and Ward's (1963) developments of the generalized exploitation of multiple linear regression and of their concept of "independent contributions" of variable sets in regression composites were based on Mood's distinction. Stimulated by these developments, two of their colleagues published a systematic application of the Bottenberg-Ward ...

ORTHOGONAL PARTITIONS OF THE 5 × 5 LATIN SQUARES

Annals of Eugenics, 1946
The articles published by the Annals of Eugenics (1925–1954) have been made available online as an historical archive intended for scholarly use. The work of eugenicists was often pervaded by prejudice against racial, ethnic and disabled groups. The online publication of this material for scholarly research purposes is not an endorsement of those views

Orthogonality and Linear Sufficiency in Partitioned and Reduced Linear Models

Communications in Statistics - Theory and Methods, 2011
The partitioned linear model ℳ12 is considered together with the reduced counterparts ℳ2 and ℳ(2), which are free from nuisance parameters present in ℳ12. The conditions are established under which the best linear unbiased estimator of parametric functions in the reduced model ℳ2(ℳ(2)) preserves its optimality in ℳ12.

Triangle Contact Systems, Orthogonal Plane Partitions, and their Hit Graphs

2001
A triangle contact system S is a geometrical object on the plane consisting of finite number of triangular disks {.si, ..., sn} in a triangle ? bounded by three segments A, B and C such that every vertex of each Si coincides with an inner point of either A, B, C or a segment of some Sj.

Automorphisms of orthogonal decompositions and of group algebras of groups with partitions

Sbornik: Mathematics, 1995
Summary: This article is devoted to an investigation of the following conjecture. If \(\{H_i\}\) is a family of subgroups that partition a finite group \(G\), then every automorphism \(\sigma\) of the group algebra \(\mathbb{C}[G]\) that permutes the subalgebras \(\mathbb{C}[H_i]\) also permutes the lines \(\mathbb{C}\cdot g\), \(g\in G\).
