students’future success to evaluate the performance criteria fed into the model.To achieve these objectives, the data for all 107 applicants (n = 107) for the Masters of Science(M.S.) in Computer Science program in the School of Engineering for Fall 2004 semester iscollected. According to the office of admissions records, the acceptance rate of the ComputerScience graduate program for the Fall 2004 semester is approximately 34 percent, with 36 accepted,and 71 rejected students.Following data collection, a DEA model to evaluate the relative efficiency of each candidate isemployed with six performance criteria, viz., the Bachelors of Science (B.S.) GPA, TOEFL andGRE Quantitative (-Q) scores, number of years of work experience, number of

hypothetical three-category Likert-style item. Subjects of low abilityare more likely to endorse the “Low” category (dark blue, e.g., 0.84 probability at θ = -2.0).Middle-ability subjects are relatively evenly split between the three options, while high-abilitysubjects display a pattern similar to that encountered for dichotomous items. At each θ value, thepredicted values sum to 1. In fact, a dichotomous response is a simplification, with only tworesponse categories (correct symbolized as P, and incorrect symbolized Q, where P + Q = 1). 1.0 0.9 0.8 0.7 Probability of response

the basis of likelihood, the final desired number of visuallysignificant scenes is determined dynamically via a user setting. The user has the ability to set thegranularity, which at one extreme selects only the most significant changes, and at the otherextreme shows all significant changes, including the least significant ones.
