Evaluation of Survival Analysis models using the AFCARS Florida dataset, reporting performance metrics such as Concordance and Log-likelihood ratio test.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | Survival Analysis |
| Dataset (including any stated split) | AFCARS Florida |
| Metric | Log-likelihood Ratio Test Value |
| Unit | OTHER |
| Direction | Higher is better |
| Results loaded | 2 of 2 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [Log-likelihood Ratio Test Value](<https://www.sota2.com/research/sota/survival-analysis-on-afcars-florida.md?metric=Log-likelihood%20Ratio%20Test%20Value>): Higher is better; unit: OTHER.

- [Concordance](<https://www.sota2.com/research/sota/survival-analysis-on-afcars-florida.md?metric=Concordance>): Higher is better; unit: SCALAR.
