Spatial Statistics

← Back to Domain-Specific Abstractions by Domain

7 domain-specific abstractions whose origin domain is Spatial Statistics.

  • Arbia's law of geography — The geographic proposition that observations aggregated at coarser spatial resolution tend to appear more mutually related than observations at finer resolution.
  • Geary's C — Measure global spatial autocorrelation by comparing weighted squared differences between neighboring observations with overall variance.
  • Moran's I — A weighted statistic measuring global spatial autocorrelation by comparing cross-products among neighboring observations with overall variance.
  • Spatial Analysis of Principal Components — A multivariate ordination method that finds genetic or ecological components maximizing variance while weighting either positive or negative spatial autocorrelation.
  • Spatial distribution — The arrangement, density and pattern of observations or phenomena across geographic space.
  • Tjøstheim's coefficient — A spatial rank-association coefficient comparing where corresponding rank levels of two variables occur across a common set of locations.
  • Wombling — Spatial statistical detection and estimation of boundaries where a modeled field changes rapidly.
