You build a model of the decision to live on campus and collect 533 students: LOC-b0+ b1 SUNIT + b2 ALCO + b3 GREK + u where LOC-1 if the student lived on campus and -0 otherwise, SUNIT is the number of academic units that the student was taking. ALCO is the nights per week that the student consumed alcohol, GREK=1 if the student was a member of a fraternity sorority, 0 otherwise, and estimate the following equation: LOC(hat)-3.26+.03SUNIT-13ALCO-39GREK
