Regression coefficients and 95% confidence intervals are reported from linear regressions of Graduation with a Ph.D. on GRE Quantitative (Column (1)), the addition of the other GRE subtests (Columns (2) and (3)) and the addition of other admissions variables (Columns (4)-(9)). Continuous variables were standardized prior to entering the models. Binary variables are shaded gray. Cohort fixed effects are included for each model. Adjusted R-squared is presented for each model.
