Variational Analysis of Paraconvex Multifunctions

Journal of Optimization Theory and Applications, 2022
In this paper, the authors aim to study the class of so-called \(\rho\)-paraconvex multifunctions from a Banach space \(X\) into the subsets of another Banach space \(Y\). These multifunctions are defined in relation with a modulus function \(\rho: X \to [0,+\infty)\) satisfying some suitable conditions.

Variational Analysis of Pseudospectra

SIAM Journal on Optimization, 2008
The $\epsilon$-pseudospectrum of a square matrix $A$ is the set of eigenvalues attainable when $A$ is perturbed by matrices of spectral norm not greater than $\epsilon$. The pseudospectral abscissa is the largest real part of such an eigenvalue, and the pseudospectral radius is the largest absolute value of such an eigenvalue.

Variational Analysis in Psychological Modeling

Journal of Optimization Theory and Applications, 2014
This paper develops some mathematical models arising in psychology and some other areas of behavioral sciences that are formalized via general preferences with variable ordering structures. Our considerations are based on the recent variational rationality approach, which unifies numerous theories in different branches of behavioral sciences using, in ...

Variation transforming analysis (I)

Applied Mathematics and Mechanics, 1980
This paper is concerned with operator variation from the transforming point of view, and presents some new concepts and new relations. Related problems and concepts include: convex operator, reciprocity set, reciprocity principles, unilateral variation principles, \((H,H_ 1,H_ 2)\)-generalized solution and operator-differential equation, etc..

Variational Analysis for the Consumer Theory

Journal of Optimization Theory and Applications, 2013
The problem under investigation is the representation of the demand correspondence as a generalized derivative of the inverse utility function. The latter is the indirect utility function under some conditions on the original utility function. Under custom conditions of classical demand theory (finite dimensionality of the goods' space, continuity and ...

Analysis of Environmental Efficiency Variation

American Journal of Agricultural Economics, 2002
AbstractIn this article, we develop and implement a methodology for analyzing the sources of variation in environmental efficiency across producers. We formulate a two‐stage model. In the first stage, we use stochastic frontier analysis to estimate both technical and environmental efficiency.

Variations on the analysis of architectural drawings

Proceedings of the Fourth International Conference on Document Analysis and Recognition, 2002
Lately, our team has begun investigating the analysis of architectural drawings. The paper presents our first results. After a brief introduction to the specificities of architectural drawings and a short review of existing work, we describe the low level processing steps we have implemented: segmentation, vectorization and detection of arcs, loops ...

EXPLAINED VARIATION IN SURVIVAL ANALYSIS

Statistics in Medicine, 1996
Several measures of explained variation have been suggested for the Cox proportional hazards regression model. We have categorized these measures into three classes which correspond to three different definitions of multiple R2 of the general linear model.
