# GitHub Contributions

Open-source contribution data derived from the Google BigQuery GitHub public dataset, with synthetic regressors and outcome.

## Benchmark Role

Sparse cross-language/project structure makes this a difficult real benchmark.

The v1 graph uses `id1` and `id2` as the two fixed-effect dimensions.

## Data

- Rows: 548,843
- Columns: `id1`, `id2`, `id3`, `t`, `len_commit_msg`, `num_files`, `x1`, `x2`, `y`
- `id1` levels: 27,970
- `id2` levels: 24,358
- CSV SHA-256: `01c617fe28aa10f0cc10f32c253340b3b0f084d5c86478e0746db1a6270d095c`
