Fit Indices for the Latent Growth Models of Energy*
| df | χ 2 | RMSEA | CFI | NNFI | |
|---|---|---|---|---|---|
| Baseline model | 55 | 153.32† | 0.08 | 0.96 | 0.93 |
| Predictive model | 85 | 240.90† | 0.08 | 0.94 | 0.93 |
In comparing the two models, the predictive model was a significantly worse fit (Δχ2 = 87.58 greater than χ2critical = 43.77), but there was little change in practical fit. RMSEA, Root Mean Square Error of Approximation.
