On the Use of Beta Coefficients in Meta-Analysis.
Journal of Applied Psychology, 2005This research reports an investigation of the use of standardized regression (beta) coefficients in meta-analyses that use correlation coefficients as the effect-size metric. The investigation consisted of analyzing more than 1,700 corresponding beta coefficients and correlation coefficients harvested from published studies.

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 ...

Hall Coefficients of Beta-Phase Alloys
Journal of the Physical Society of Japan, 1969The Hall coefficients ( R H ) and the electrical resistivities (ρ) of three beta-phase alloys CuZn, AgCd and AgZn, which undergo the order-disorder transformation, were measured from room temperature to about 615°C. Experiments showed: 1. R H of the ordered (β') phase connects continuously with that of the disordered (β) phase, at the transition ...

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 ...

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 ...

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

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.
