Reliability Estimation Using Validity Coefficients
The Journal of Experimental Education, 1986Occasionally 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, 2010We 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.

On Squaring Validity Coefficients
Educational and Psychological Measurement, 1977The 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, 2017Human‐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).

The use of correlation coefficients in test validation
Higher Education, 1987Although 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.

Validated Bounds for Taylor Coefficients of Analytic Functions
Reliable Computing, 2001The 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.

Validity Coefficients and Correlated Errors in Test Theory
The Journal of Experimental Education, 1977Simple formulas for test validity in predictor-criterion test situations are derived from the expected-value concept of true score without assuming that error scores on distinct tests are uncorrelated. The formulas apply when scores are not experimentally independent and reduce to the usual results of the classical model if the correlation between ...

Assay Validation Using the Concordance Correlation Coefficient
Biometrics, 1992A new reproducibility index, called the concordance correlation coefficient, has been proposed (Lin, 1989, Biometrics 45, 255-268) to evaluate the reproducibility of an assay, method, or instrument. This index includes measurements of precision and accuracy. Based on certain criteria about the allowable losses in precision and accuracy, one can compute

Organizational Research Methods, 2007
The sample squared multiple correlation coefficient is widely used for describing the usefulness of a multiple linear regression model in many areas of science. In this article, the author considers the problem of estimating the squared multiple correlation coefficient and the squared cross-validity coefficient under the assumption that the response ...
