TABLE 5.
Most important decision rules in five‐time random modelling.
| No. | Condition (IF) | Decision (then) | Support size | Laplace |
|---|---|---|---|---|
| 1 | IF [SE 3 is 5] and [SR 2 is 5] and [O 5 is 5] | 5 | 18 | 0.9048 |
| 2 | IF [C 4 is 5] and [SE 3 is 5] | 5 | 18 | 0.9048 |
| 3 | IF [SA 1 is 5] and [O 5 is 5] | 5 | 17 | 0.9 |
| 4 | IF [C 4 is 5] and [SE 3 is 5] | 5 | 15 | 0.8889 |
| 5 | IF [C 4 is 5] and [SA 1 is 5] and [SA 3 is 5] | 5 | 15 | 0.8889 |
| 6 | IF [SE 3 is 5] and [SA 1 is 5] and [O 4 is 5] | 5 | 12 | 0.8667 |
| 7 | IF [SA 1 is 5] and [O 5 is 5] and [SR 2 is 5] | 5 | 17 | 0.9 |
| 8 | IF [T 1 is 5] and [C 4 is 5] and [O 5 is 5] and [SA 1 is 5] | 5 | 14 | 0.8824 |
| 9 | IF [O 4 is 5] and [O 3 is 5] and [SE 3 is 5] | 5 | 16 | 0.8947 |
Note: 1 = strongly disagree, 2 = disagree, 3 = uncertain, 4 = agree, 5 = strongly agree. Support size: Number of samples supporting this rule. Laplace: The larger the number, the higher the laplace.
Among the nine most important rules, the conditional attribute plays a key role in indicating the conditions, situations, and behaviours under which the corresponding results (i.e., decisions) are produced. Based on these rules, nine conditional attributes were identified: SE 3 (five times), SA 1 (five times), O 5 (four times), C 4 (four times), SR 2 (two times), O 4 (two times), SA 3 (once), T 1 (once), and O 3 (once).
