Reliability Estimation Using Validity Coefficients

The Journal of Experimental Education, 1986
Occasionally situations arise in which a measurement does not lend itself to such traditional methods of reliability estimation as the test-retest, parallel-test, or internal consistency methods, for example, because a single item variable or an index based on heterogeneous data is involved.

VALIDATING SYNTHETIC VALIDATION: COMPARING TRADITIONAL AND SYNTHETIC VALIDITY COEFFICIENTS

Personnel Psychology, 2010
We describe a unique application of a synthetic validation technique to a selection system development project in a large organization. Job analysis data were collected from 4,725 job incumbents and 619 supervisors, and were used to identify 11 job families and 27 job components.

The use of correlation coefficients in test validation

Higher Education, 1987
Although the Pearson Product Moment Correlation Coefficient, r, is commonly used in student selection, it is argued here, that it is frequently more appropriate to use the Bi-serial Correlation Coefficient rbis for this purpose.

On Squaring Validity Coefficients

Educational and Psychological Measurement, 1977
The squared validity coefficient appropriately describes the proportion of variance in a criterion measure explained by a predictor when the predictor precisely measures its target construct and is linearly related to the criterion. Since neither of these conditions is closely realized in psychological measurement, the squared validity coefficient is ...

Is a .51 validity coefficient good? Value sensitivity for interview validity

International Journal of Selection and Assessment, 2017
Human‐resource professionals (n = 201) were presented with meta‐analytic validity coefficients associated with unstructured and structured employment interviews. When presented alone, the unstructured interview received a higher effectiveness rating—despite having a smaller validity coefficient—than the structured interview received (d = −.30).

On the validity of the kubo formulae for transport coefficients

Physics Letters, 1963
Attempts have been made to express transport coefficients in terms of time correlation functions. The validity of these expressions is examined by studying the viscosity coefficient of a diffuse simple gas in classical theory. In the lowest order of density the viscosity relation reduces to the Chapman-Enskog result.

Customised birthweight: Coefficients for an Australian population and validation of the model

Australian and New Zealand Journal of Obstetrics and Gynaecology, 2006
AbstractBackground:  Published birthweight references in Australia do not fully take into account constitutional factors that influence birthweight and therefore may not provide an accurate reference to identify the infant with abnormal growth. Furthermore, studies in other regions that have derived adjusted (customised) birthweight references have ...

Validated Bounds for Taylor Coefficients of Analytic Functions

Reliable Computing, 2001
The author obtains rigorous bounds for the Taylor coefficients of analytic functions. The methods are based on interval arithmetic and modified versions of Cauchy's estimate. Interval arithmetic is a subject described, for instance, in the following books: \textit{M. S. Petkovic} and \textit{L. D.

Validation of the Salt Diffusion Coefficient in Porous Materials

2003
The durability of porous building materials largely depends on the transport of liquids and dissolved salts into the material. When the moisture dries out, salts will crystallise introducing important forces in the solid matrix of the porous material. These interaction forces may result in cracking of the material.
