A new regression-based method of assessing test bias is proposed. We highlight two different potential causes of differences in groups' regression line intercepts. Intercepts differing due to mean criterion score differences are not interpreted as predictive test bias. Using both simulated and employee data, we illustrate this new approach. Test bias is a systematic error in how a test measures...

abstract aim and background: mind reading as an ability of interfering mental state of others has an essential role in social interactions. the purpose of the present study is designing farsi version of reading the mind from the voice and evaluation of psychometric properties of it. methods and materials: in the present correlation study, twenty hundred sixteen students of shahid beheshti and t...

Examination over multiple horizons has been a routine in testing asset return predictability in finance and macroeconomics. In a simple predictive regression model, we find that the popular scaled test for multiple-horizon predictability has zero null rejection rate if the forecast horizon increases at a faster rate than the inverse of proximity of the predictor autoregressive root to the unity...

Ambulatory children and youth with cerebral palsy have limitations in locomotor capacities and in community mobility. The ability of three locomotor tests to predict community mobility in this population (N = 49, 27 boys, 6-16 years old) was examined. The tests were a level ground walking test, the 6-min-Walk-Test (6MWT), and two tests of advanced locomotor capacities, the 10-meter-Shuttle-Run-...

Blanton and Jaccard (2006) questioned the 4-test regression method used by Greenwald et al. (2002) to test a pure multiplicative theory. The present authors address Blanton and Jaccard’s concerns with a combination of simulations and meta-analysis. Simulations show that (a) Blanton and Jaccard’s preferred simultaneous regression method has a severe power loss in testing multiplicative theories ...

This paper compares the determination of optimal cutoff points for single and multiple tests in the field of personnel selection. Decisional skills of predictor tests composing the multiple test are assumed to be endogenous variables that depend on the cutting points to be set. It is shown how the predictor cutoffs and the collective decision rule are determined dependently by maximizing the mu...

The molecular diversity of breast cancer makes it impossible to identify prognostic markers that are applicable to all breast cancers. To overcome limitations of previous multigene prognostic classifiers, we propose a new dynamic predictor: instead of using a single universal training cohort and an identical list of informative genes to predict the prognosis of new cases, a case-specific predic...

objective: the measurement of follicular output rate (fort) has been proposed as a good indicator for evaluating follicular response to the exogenous recombinant folliclestimulating hormone (rfsh). this places fort as a promising qualitative marker for ovarian function. the objective of the study was to determine fort as a predictor of oocyte competence, embryo quality and clinical pregnancy af...
