    This study applies a spatial aggregation methodology to gravity models, linking interaction data patterns to model parameters. The approach is demonstrated using population density models in England's Reading region.

    Area of Science:

    • Spatial analysis
    • Geographic information systems
    • Econometrics

    Background:

    • Spatial aggregation presents challenges in gravity model accuracy.
    • Previous work established a framework for analyzing spatial aggregation.
    • Interaction data requires robust methods for spatial pattern analysis.

    Purpose of the Study:

    • To apply a spatial aggregation analysis methodology to gravity models.
    • To link spatial patterns in interaction data to model parameters.
    • To demonstrate the application using a continuous one-dimensional interaction model.

    Main Methods:

    • Utilizing a consistent framework for linking spatial pattern measures to interaction models.
    • Deriving and estimating interaction models informed by spatial information.
