Introductory, in section 1, it was argued that the number forecast rules decreases as the order increases in high order models. This is evident from table 30, when considering the forecasted enrollments by the two models by Chen/Chung [15] and Kuo et al [30], as it can be noted that the first 7 - 8 years of enrollment are not forecasted. Moreover, by increasing the order, additional combinations of patterns (fuzzy sets) have to be matched which reduces the probability of finding equivalent pattern combinations in future data.
