Test Pass/Fail Judgment and Japanese Compact Cars and Regular Cars

I introduce two self-evident LSDs. The pass/fail judgments of exams are self-evident LSD. Suppose two scores, T1 and T2, and 50 points is the passing score. LDF, f(T) = T1 + T2 − 49.5, can find LSD. Applicants pass if f > 0 and fail if f < 0. Exams have the same data structure as microarrays in two respects: (1) a single measure of score and amount of protein. (2) Many cases correctly separate into two groups near the linear hyperplane. In other words, microarrays are simple discrimination like exams. However, in Theory2, I spent much research time solving the difficulty of “many combinations.” On the other hand, for exams, Program3 and Program4 can find SMs and BGSs, and Program2 evaluates the BGS with the smallest M2. Then, the exam specialists investigate the relationship between students’ answer patterns and the difficulty level of the questions. Japanese regular and compact cars are determined by two standards: engine displacement and number of seats. Those are two trivial BGSs. I believe many products have industry standards that become univariate BGSs. We can find obvious LSD if we have a strong will to find LSD. Moreover, we find many BGSs from the species of animals and plants.
