Fig. 7
Probability of college admission and test scores. This figure shows the relationship between birthday and college admission (on the left), as well as between the birthday and the college entrance test score (on the right). The center of the graphs is zero, which represents January 1. The first graphs at the top show the relationship for boys, and the ones at the bottom show that for girls. Data come from applications for undergraduate programs at UFPE from 2002 to 2005. The sample is restricted to those who graduated from high school in the same year and were under 18.5 years old. Functions are estimated using a triangular kernel with the bandwidth selection procedure proposed by Calonico et al. (2014). Ï„ is the RD estimate, with robust standard errors in parentheses. ***, **, * represent statistical significance at the 1, 5, and 10 % levels, respectively
