A sоciоlоgist hаs estimаted а linear model for the association between academic test scores, gender and father’s years of education using OLS regression and obtained the following estimates and OLS standard errors. A colleague points out that the students in the sample are clustered within classrooms. Therefore the sociologists re-runs the OLS regression using Liang-Zeger cluster-robust standard errors. The equation below shows the new (cluster-robust) standard errors. What values does the sociologist obtain for the coefficients on Female and DadEduc?
