Connectedness feature reference
How unusual the number of neighbours sharing figures with the focal place is relative to degree-preserving randomised place–figure networks.
Stored model field:
shared_figure_neighbor_zscore
Use the same fixed-neighbour, degree-preserving place–figure rewirings as the shared-figure count null model, but compare the observed number of figure-sharing neighbours with its null mean and standard deviation. The current build uses 20 seeded samples.
More neighbours share figures with the place than expected under the null model.
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 | -1.264 | +0.000 | +0.000 | +1.151 | +0.017 | +41.065 |
| Survives | 204 | -1.264 | +0.000 | +0.000 | +1.229 | +0.000 | +41.065 |
| Does not survive | 51 | -0.822 | +0.000 | +0.000 | +0.841 | +0.819 | +8.947 |
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.

Its current standardized coefficient is +0.721, pointing toward survives. 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 association—not a standalone ranking, causal effect, or historical explanation.
