Coefficient Beta and Hierarchical Item Clustering
Organizational Research Methods, 2006Summated scales are widely used in management research to measure constructs such as job satisfaction and organizational commitment. This article suggests that Revelle’s (1979) coefficient beta, implemented in Revelle’s (1978) ICLUST item-clustering procedure, should be used in conjunction with Cronbach’s coefficient alpha measure of internal ...

Further Evidence on the Stationarity of Beta Coefficients
The Journal of Financial and Quantitative Analysis, 1978Diversification and capital market theory in conjunction with investors' desire to quantify risk have caused the beta coefficient to receive considerable attention in recent finance literature. Results of empirical investigations of the stationarity of beta over time have been reported by Altman, Jacquillat, and Levasseur [1], Baesel [2], Blume [3 ...

New risks in the new beta coefficient: Behavioral approach
Risk and Decision Analysis, 2021The article addresses theoretical issues, applied instruments and practical implementation of the behavioral valuation methodology. It formulates the range of specific correction parameters for beta coefficient, used in calculating CAPM-based discount rate in order to find behavioral discount rate and calculate stock’s market value, with regard to ...

Coefficients Alpha, Beta, Omega, and the glb: Comments on Sijtsma
Psychometrika, 2009There 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 ...

A Beta-Optimal Test of the Equicorrelation Coefficient
1989This paper considers the problem of testing for nonzero values of the equicorrelation coefficient of a standard symmetric multivariate normal distribution. Recently, SenGupta (1987) proposed a locally best test. We construct a beta-optimal test and present selected one and five per cent critical values.

THE ACCOUNTING BETA COEFFICIENT CAN BE USED AS A PROXY FOR THE MARKET BETA COEFFICIENT
Journal of Monetary Economics and ManagementПри оценке привлекательности инвестиции помимо будущей доходности необходим учет риска. Одной из классических моделей оценки риска вложения в собственный капитал является модель CAPM. Ограниче- нием модели является её невозможность использования в неизменном виде при применении к компаниям, не имеющим данные по торгуемым ценам на акции. В этом случае в

Some evidence on the stability of beta coefficients on the JSE
South African Journal of Accounting Research, 1997Knowledge of beta stability is crucial for projections involving the use of beta coefficients, in particular, in the areas of project evaluation and portfolio design. This paper investigates the issue of beta stability on the JSE. The investigation reveals how spurious inferences on stability can be made if estimation techniques do not correct for thin

Calculation of Mass Attenuation Coefficients of Beta Particles
Radiation Protection Dosimetry, 1998Using the semi-empirical equations for the transmission coefficient of monoenergetic electrons, the mass attenuation coefficient of beta particles has been calculated. Beta spectra for 'allowed' and 'first forbidden' transitions are considered. The calculated mass attenuation coefficients for {beta}- emitters determined in the present study agree ...
