Table 5. Selected parameter estimates from models 1 to 4.
Race coefficient estimates, their effect sizes, and variance components estimates from four hierarchical linear models for preliminary overall impact scores fit on n = 7471 reviews of 2566 applications. Model 1 controls for structural covariates; model 2 controls for structural and applicant/application-specific covariates; model 3 controls for structural covariates and criterion scores; model 4 controls for structural and applicant/application-specific covariates and criterion scores. Control variables are listed in Table 1. Coefficient estimates for control variables are not shown. Significance * is reported for P < 0.005. In mixed-effects models, multiple effect sizes exist for a given coefficient; we report the coefficient divided by the residual SD. For more information, see (49).
