Econometrics is required for all senior seminars with the exception of the seminar for the joint major with philosophy. Hence, majors cannot take econometrics in their final semester. In addition, a number of the electives in the department assume that students are familiar with basic concepts from both statistics and econometrics. Hence, students who would like to take econometrics in the fall semester of their senior year must have the written approval from the Director of Undergraduate Studies in the Economics Department.
