Connectedness feature reference
The number of distinct places joined directly to the focal place in the constructed place graph.
Stored model field:
direct_place_neighbor_count
Count adjacent place nodes created from eligible MANTO place-to-place relationships, including the constructed somewhere-in-or-near edge between a place and its recorded parent locality.
The focal place has direct graph ties to more other places.
These descriptive statistics use the current labelled cohort after aliases have been collapsed to one row per MANTO place.
| Group | N | Minimum | Q1 | Median | Mean | Q3 | Maximum |
|---|---|---|---|---|---|---|---|
| All labelled places | 255 | 0 | 0 | 1 | 5 | 6 | 89 |
| Survives | 204 | 0 | 0 | 1 | 4 | 5 | 38 |
| Does not survive | 51 | 0 | 0 | 1 | 7 | 8 | 89 |
Examples are descriptive checks on the calculated feature. Their outcome labels report what Pausanias says; they do not establish that the feature caused survival or abandonment.
| Place | MANTO ID | Value | Pausanias reports |
|---|---|---|---|
| π Thebes (Boiotia) | 8253960 | 89 | Does not survive |
| π Libya (North Africa) | 8253951 | 43 | Does not survive |
| π Thessaly | 9055627 | 38 | Survives |
| π Arcadia | 8228863 | 37 | Survives |
| π Argos (city) | 8228853 | 36 | Survives |
| π Boiotia | 8195196 | 33 | Does not survive |
| Place | MANTO ID | Value | Pausanias reports |
|---|---|---|---|
| π Acharnai (Attica) | 10153056 | 0 | Survives |
| π Acriai (Laconia) | 10149418 | 0 | Survives |
| π Agrai (Attica) | 10151548 | 0 | Survives |
| π Aigai (Macedonia) | 11321421 | 0 | Does not survive |
| π Aigiai (Laconia) | 10146647 | 0 | Survives |
| π Aigialeia (alt. Sicyon) | 10157818 | 0 | Survives |
Its current standardized coefficient is -0.394, pointing toward does not survive. This means that a one-standard-deviation increase changes the fitted log odds in that direction while the other included features are held fixed.
Because the connectedness features are correlated and the model's out-of-fold performance is weak, this is a conditional associationβnot a standalone ranking, causal effect, or historical explanation.
