     Data from a study by the _U.S. News and World Report_ magazine
     with the purpose of college ranking. Druzdzel and Glymour choose 8
     variables and after removing some universities give a correlation
     matrix for 170 universities. The 8 variables are:

     __a_p_g_r_a_ average percentage of graduation, i.e., the fraction of
          the total number of entering students who make it through the
          graduation,

     __r_e_j_r_ rejection rate, i.e., the fraction of the applicants who
          are given an admission offer,

     __t_s_t_s_c_ average standardized test scores of the incoming students,

     __t_o_p_1_0_ class standing of the incoming freshman, which is a
          fraction of the incoming freshmen who were in top 10% of
          their high school graduating class,

     __p_a_c_c_ percentage of those students who accept the university's
          offer from among those who are offered admission,

     __s_p_e_n_d_ total educational and general expenses per student, which
          is the sum spent on the instruction, student services, and
          academic support, including libraries and computing services, 

     __s_t_r_a_t_ student-faculty ratio,

     __s_a_l_a_r_ average facutly salary.
