Summary of the information criteria for the ξCDM and wξCDM models compared to the flat ΛCDM model, utilizing the combined dataset CC+BAO+SNeIa with consideration of three distinct samples of SNeIa.
| Model | ΔAIC | ΔBIC | ln(BF) |
|---|---|---|---|
| CC+BAO+PP | |||
| ΛCDM | − | − | − |
| ξCDM | 0.74 | −4.72 | −1.60 |
| wξCDM | −1.34 | −12.26 | −0.16 |
| CC+BAO+PPNoS | |||
| ΛCDM | − | − | − |
| ξCDM | −2.21 | −7.60 | 0.97 |
| wξCDM | −4.29 | −15.06 | 2.26 |
| CC+BAO+P | |||
| ΛCDM | − | − | − |
| ξCDM | −1.99 | −4.24 | 0.79 |
| wξCDM | −3.92 | −8.41 | 1.92 |
Notes. The AIC indicates a preference for ΛCDM, albeit weaker when Cepheids are included. Conversely, the BIC strongly favors ΛCDM. Additionally, the BF demonstrates a weak preference for the IDE models in the combined analysis CC+BAO+PP.
