Selection of the number of classes in latent class analysis. The BIC and the CAIC are criterion for model selection. Good models (e.g., the true model or nearly true models) have relatively small BIC and CAIC values.
| No. Classes | BIC | CAIC |
|---|---|---|
| 2 | 868.0 | 926.0 |
| 3 | 895.3 | 983.3 |
| 4 | 932.4 | 1050.4 |
| 5 | 1004.8 | 1152.8 |
