Spatial analysis

By e2er authors

How a variable varies across regions or places: maps from the data and recorded boundaries, Moran's I with permutation inference recomputed by e2er, optional local clusters (LISA), with the boundaries' source, CRS and weights checked before the analysis.

Input
A question about how a variable varies across places, data by region and their boundaries
Output
Maps, Moran's I with permutation inference and optional local clusters, as a draft paper with a dossier
At the end
When any run ends, e2er builds the PDF, writes the audit trail and the structured export, and pushes to GitHub if you set that up.

Steps

Greyed steps do not run in the selected mode.

  1. 1
    Boundaries, CRS and weights check
    After the data are loaded. The data architect writes spatial_design.json (units, boundaries and their source, CRS, spatial weights; schema in skills/files/data/spatial-statistics.md). The check stops the run when the boundaries' source is not recorded, the CRS is missing or does not fit the coordinates, a unit of the data has no geometry and is not listed with a reason, or the weights are not documented. A failed check sends the data architect back once with the reasons, then stops the run..

  2. 2
    Moran's I and maps check
    After the analysis, before drafting. The analysis writes the units and values it used (spatial_units.csv) and its weights (spatial_weights.csv); the check recomputes every Moran's I from them, requires permutation inference, and builds a map figure for every map the results name (choropleth or categories, from the boundaries in data.db; rendered by src/core/renderer/maps.py). A failed check sends the econometrics specialist back once..
