A robust partial least squares method with applications [PDF]
Partial least squares regression (PLS) is a linear regression technique developed to relate many regressors to one or several response variables. Robust methods are introduced to reduce or remove the effect of outlying data points.

Homoclinic orbits in 3D dissipative systems [PDF]
The paper deals with a variational system corresponding to a three-dimensional dynamic system. The characteristic equation of the variational system depends on partial solutions. The matrix of the right-hand part of the variational system is a sum of two

Purpose. Warm hepatic ischemia-reperfusion (I/R) injury can lead to multiorgan dysfunction. The aim of the present study was to investigate whether acute liver I/R does affect the function and/or structure of remote organs such as lung, kidney, and heart

Matrix Theorems for Partial Differential and Difference Equations.
We extend the work of Kreiss and Morton to prove: for some constant K(m), where m is the order of the matrix A, $|A^(n)v| \leq C(v)$ for all n $geq$ 0 and |v| = 1 implies that $|{SAS}^{-1}| \leq 1$ for some S with $|S^{-1}| \leq 1$, |Sv| $\leq$ k(m)C(v).

Partial parameterization of orthogonal wavelet matrix filters
In this paper we propose a procedure which allows the construction of a large family of FIR d x d matrix wavelet filters by exploiting the one-to-one correspondence between QMF systems and orthogonal operators which commute with the shifts by two. A characterization of the class of filters of full rank type that can be obtained with such procedure is ...

Partial Algebras and Implications of (Weak) Matrix Properties
AbstractMatrix properties are a type of property of categories which includes the ones of being Mal’tsev, arithmetical, majority, unital, strongly unital, and subtractive. Recently, an algorithm has been developed to determine implications $$\textrm{M}\Rightarrow _{\textrm{lex}_*}\textrm{N}$$ M

The manifest association structure of the single-factor model: insights from partial correlations [PDF]
The association structure between manifest variables arising from the single-factor model is investigated using partial correlations. The additional insights to the practitioner provided by partial correlations for detecting a single-factor model are ...
