  1. Notes: Each of the peer group ability definition groupings and each column contains coefficient estimates from separate regressions. All peer measures are standardized. Each regression also contains controls for race/ethnicity, SAT I math and verbal scores, UC-adjusted high school GPA, parental education, family income by cohort, college, college selectivity tier by cohort, and UC application-admission pattern fixed effects that account for the intended major listed on each application. Robust standard errors, clustered by campus, are reported in brackets. ***p < 0.01, **p < 0.05, *p < 0.1, based on a t-distribution with 5 d.f.
