Table A1 Value Patterns and Computations of Expected Frequencies Based on an Independence Model of Absence or Presence of RepNSSI at Three Age Levels. The Computations Were Made from Marginal Frequencies in a Three-Way Contingency Table (N = 475)
| Â | Â | RepNSSI at T3 | |
|---|---|---|---|
RepNSSI at T1 | RepNSSI at T2 | 0 (n = 428) | 1 (n = 47) |
0 (n = 400) | 0 (n = 372) | Value pattern: 000 \(\frac{400}{475}\times \frac{372}{475}\times 428\) | Value pattern: 001 \(\frac{400}{475}\times \frac{372}{475}\times 47\) |
|  | 1 (n = 103) | Value pattern: 010 \(\frac{400}{475}\times \frac{103}{475}\times 428\) | Value pattern: 011 \(\frac{400}{475}\times \frac{103}{475}\times 47\) |
1 (n = 75) | 0 (n = 372) | Value pattern: 100 \(\frac{75}{475}\times \frac{372}{475}\times 428\) | Value pattern: 101 \(\frac{75}{475}\times \frac{372}{475}\times 47\) |
|  | 1 (n = 103) | Value pattern: 110 \(\frac{75}{475}\times \frac{103}{475}\times 428\) | Value pattern: 111 \(\frac{75}{475}\times \frac{103}{475}\times 47\) |
