Combinatorial Designs with Two Singular Values II. Partial Geometric Designs
In this and an earlier paper [17] we study combinatorial designs whose incidence matrix has two distinct singular values.These generalize (v, k, ë) designs, and include uniform multiplicative designs and partial geometric designs.Here we study the latter,

ℋ-Matrix preconditioners in convection-dominated problems
, 2006 Hierarchical matrices provide a data-sparse way to approximate fully populated matrices. In this paper we exploit ℋ-matrix techniques to approximate the LU-decompositions of stiffness matrices as they appear in (finite element or finite difference ...

The Combinatorially Symmetric Partial N-matrix Completion
, 2006 主要讨论了部分Toeplitz N-矩阵的完成问题及一类特殊结构的位置对称的部分N矩阵的完成.An n-by-n matrix is called an N-matrix if all principal minors are negative. In this paper, we are interested in the partial Toeplitz N-matrix completion problem, and study some combinatorially symmetric ...

Difference based Ridge and Liu type Estimators in Semiparametric Regression Models [PDF]
We consider a difference based ridge regression estimator and a Liu type estimator of the regression parameters in the partial linear semiparametric regression model, y = Xβ + f + ε.

ROBUST COVARIANCE MATRIX ESTIMATION: "HAC" Estimates with Long Memory/Antipersistence Correction [PDF]
Smoothed nonparametric estimates of the spectral density matrix at zero frequency have been widely used in econometric inference, because they can consistently estimate the covariance matrix of a partial sum of a possibly dependent vector process.
