Coefficient Omega Bootstrap Confidence Intervals

Educational and Psychological Measurement, 2013
The performance of the normal theory bootstrap (NTB), the percentile bootstrap (PB), and the bias-corrected and accelerated (BCa) bootstrap confidence intervals (CIs) for coefficient omega was assessed through a Monte Carlo simulation under conditions not previously investigated. Of particular interests were nonnormal Likert-type and binary items. The

Evaluation of Dimensionality in the Assessment of Internal Consistency Reliability: Coefficient Alpha and Omega Coefficients

Educational Measurement: Issues and Practice, 2015
In the lead article, Davenport, Davison, Liou, & Love demonstrate the relationship among homogeneity, internal consistency, and coefficient alpha, and also distinguish among them. These distinctions are important because too often coefficient alpha—a reliability coefficient—is interpreted as an index of homogeneity or internal consistency. We argue

Coefficient Omega

Journal of Nursing Education, 2021
This article raises the concern that nursing education research may be unduly subject to several limitations inherited from an overreliance on Cronbach's α. Consequently, researchers are encouraged to make greater use of coefficient omega since it is expected to perform just as well as or better than Cronbach's α, especially when tau ...

General $\Omega $-theorems for coefficients of $L$-functions

Proceedings of the American Mathematical Society, 2015
The paper under review proves a general \(\Omega\)-theorem for the sum of the coefficients of polynomial combinations of \(L\)-functions from the Selberg class \(\mathcal{S}\) of Dirichlet series with functional equation and Euler product. More precisely, fix a polynomial \(P\in \mathbb{C}[X_1,\ldots, X_N]\) and \(F_1,\ldots, F_N\in \mathcal{S}\), and ...

Coefficients Alpha, Beta, Omega, and the glb: Comments on Sijtsma

Psychometrika, 2009
There are three fundamental problems in Sijtsma (Psychometrika, 2008): (1) contrary to the name, the glb is not the greatest lower bound of reliability but rather is systematically less than ωt (McDonald, Test theory: A unified treatment, Erlbaum, Hillsdale, 1999), (2) we agree with Sijtsma that when considering how well a test measures one concept, α ...

Estimating the Strength of a General Factor: Coefficient Omega Hierarchical

Industrial and Organizational Psychology, 2015
Relying on work described by Jackson (2003), Ree, Carretta, and Teachout (2015) recommended researchers use the first unrotated principal component associated with a principal components analysis (PCA) to estimate the strength of a general factor. Arguably, such a recommendation is based on rather old work.

THE COEFFICIENTS OF THE ω(q) MOCK THETA FUNCTION

International Journal of Number Theory, 2008
In 1920, Ramanujan wrote to Hardy about his discovery of the mock theta functions. In the years since, there has been much work in understanding the transformation properties and asymptotic nature of these functions. Recently, Zwegers proved a relationship between mock theta functions and vector-valued modular forms, and Bringmann and Ono used the ...

Derivation of Beam Interpolation Coefficients with Application to the K-omega Beamformer

2001
Abstract : A problem of general interest is to be able to use a set of L beams, steered and focused respectively at the bearing-range pairs Theta1, R1, Theta2, R2,..., Theta(sub L), R(sub L), to approximate a beam steered and focused at a given angle-range pair Theta0, R0.
