Evaluation of model performance on predicting population subgroup responses using the test split of the SubPOP dataset.

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 | Population Subgroup Response Prediction |
| Dataset (including any stated split) | SubPOP (test) |
| Metric | WD |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 4 of 4 |
| 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

- [WD](<https://www.sota2.com/research/sota/population-subgroup-response-prediction-on-subpop-test.md?metric=WD>): Lower is better; unit: SCALAR.
