About this dataset
Eight synthetic training records with original values 2 through 9. Hide exactly two. Fill values use only observed entries; original values are teaching-only ground truth. There is no model or held-out evaluation in this demonstration.
- Small deterministic teaching fixture; no random sampling or population inference.
- The explorer shows reference inputs. Each run report includes its own inputs and calculated evidence.
Counts exclude the row identifier. Duplicate counts are extra occurrences after the first. Feature duplicates ignore labels and experimental conditions. — means a statistic is undefined or not applicable.
- Row
- Stable record identifier, not a model feature.

- Original value
- Teaching-only truth. Never used to calculate an imputation value.
