A Note on Exploratory Item Factor Analysis by Singular Value Decomposition [PDF]

open access: yesPsychometrika, 2019
We revisit a singular value decomposition (SVD) algorithm given in Chen et al. (Psychometrika 84:124–146, 2019b) for exploratory item factor analysis (IFA).

Patterns and Drivers of Spanish Corporate Commitment to the UN Global Compact: A Quantitative Approach

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This paper presents a quantitative assessment of Spanish companies' commitment to the United Nations Global Compact (UNGC) and the Sustainable Development Goals (SDGs). Analyzing over 1000 participating firms, we identify prioritization patterns and examine structural factors influencing SDG adherence.

Condition of a linear system [PDF]

open access: yes, 2009
U ovom članku analizira se uvjetovanost matrice linearnog sustava i njena povezanost sa singularnom dekompozicijom matrice. Pokazuje se da su loše uvjetovane matrice "gotovo singularne". Singularna dekompozicija također ukazuje na tu vezu, a koristi se i

Radar Signals Compression using Singular Value Decomposition (SVD) Approach

open access: yesInternational Journal of Computer Applications, 2016
ability to reduce noise in a received radar signal from its target largely indicates the accuracy of the radar system. Matched filters help to maximize the signal to noise ratio of radar systems. Matched Filters are commonly used in radars whose transmitted signals are known and are used as a replica to correlate with the received signal.

Gaborlet‐guided sparse filtering: A novel intelligent method for lithology identification by vibration signals while drilling

open access: yesDeep Underground Science and Engineering, EarlyView.
The flowchart illustrates rock specimen testing, vibration signal acquisition, and feature extraction with Gaborlet and sparse filtering for classification. Abstract Traditional lithology identification methods mainly rely on core sampling and well‐logging data.

Efficient singular-value decomposition of the coupled-cluster triple excitation amplitudes

open access: yes, 2019
We demonstrate a novel technique to obtain singular-value decomposition (SVD) of the coupled-cluster triple excitations amplitudes, $t_{ijk}^{abc}$. The presented method is based on the Golub-Kahan bidiagonalisation strategy and does not require $t_{ijk}^

The Black‐Box of ESG Scores From Rating Agencies: Do They Genuinely Reflect Sustainability Practices, or Are They Disproportionately Shaped by Financial Performance?

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT This study examines the environmental, social and governance (ESG) scoring methodologies used by Bloomberg and S&P Global through the lens of Data Envelopment Analysis (DEA). It addresses a notable gap in the literature by identifying the underlying factors that shape ESG scores and providing practical insights for companies seeking to ...

The Singular Value Expansion for Arbitrary Bounded Linear Operators

open access: yesMathematics, 2020
The singular value decomposition (SVD) is a basic tool for analyzing matrices. Regarding a general matrix as defining a linear operator and choosing appropriate orthonormal bases for the domain and co-domain allows the operator to be represented as ...
