(3) Example of eight indicator selection (Fig. 6)
Indicators: Debt composition ratio, Grant dependency ratio, Education expenses ratio, Research expenses ratio, Research expenses per full-time faculty member, Growth rate of operating income, Personnel expenses ratio, Self-generated income ratio.
Normalized Entropy: 0.724.
Accuracy: 0.913.
Although the accuracy and whole entropy have improved, as can be seen from Fig. 5 and 6,
there is little change in entropy of each class.
Therefore, the data structure is thought to be similar to that in Figure 5.
