Table 2.
SEM results for the best model obtained for the clear and turbid data sets.
| Statistic | Clear | Turbid |
|---|---|---|
| Akaike information criterion (AIC) | 1,162.1 | 883.5 |
| Bayesian information criterion (BIC) | 1,251.4 | 933.2 |
| Sample‐size adjusted BIC (n* = (n + 2)/24) | 1,119.2 | 863.9 |
| χ2 | 31.9 | 13.72 |
| P | 0.0598 | 0.6867 |
| RMSEA | 0.09 | <0.01 |
| P | 0.149 | 0.824 |
| CFI | 0.951 | 0.999 |
The χ2 is for goodness of fit (P < 0.05 indicates model significantly different from the empirical data); RMSEA, root mean square error of approximation (close to zero is good fit and P tests for difference from zero); CFI, comparative fit index (ranges 0–1, with 1 being a perfect fit).
