TLDR
It is demonstrated that zoning-system effects on parameter values and model performance are nontrivial, and that their magnitude is far larger than was previously thought likely.Abstract:
The design of zoning systems for spatial interaction models is a major problem which affects both the interpretation and acceptability of these models. This paper demonstrates that zoning-system effects on parameter values and model performance are nontrivial, and that their magnitude is far larger than was previously thought likely. An approach which is most appropriate in an applied context, where there is also the problem of poor model performance, is to identify a zoning system which will approximately optimise model performance. The paper gives details of how this may be achieved. This method is demonstrated by a series of empirical studies. Finally, there is a brief discussion of the general implications for spatial model building.read more

The Modifiable Areal Unit Problem in Multivariate Statistical Analysis
A S Fotheringham,David Wong +1 more
TL;DR: The modifiable areal unit problem is shown to be essentially unpredictable in its intensity and effects in multivariate statistical analysis and is therefore a much greater problem than in univariate or bivariate analysis.

The modifiable areal unit problem and implications for landscape ecology
Dennis E. Jelinski,Jianguo Wu +1 more
TL;DR: The Modifiable Areal Unit Problem (MAUP) as discussed by the authors applies to two separate, but interrelated, problems with spatial data analysis, where the same set of areal data is aggregated into several sets of larger areal units with each combination leading to different data values and inferences.
Journal ArticleDOI
A new set of spatial-interaction models: the theory of competing destinations.
TL;DR: Members of the family of spatial-interaction models commonly referred to as gravity models are shown to be misspecified and an undesirable ‘spatial-structure effect’ in estimated distance-decay parameters is examined.

Analysis of Urban Growth and Sprawl from Remote Sensing Data
TL;DR: In this paper, the authors provide a comprehensive discussion on urban growth and sprawl, and how they can be analyzed using remote sensing imageries; their patterns, process, causes, consequences, and countermeasures; and what are the merits and demerits of available methods and models.

Constructing the Spatial Weights Matrix Using a Local Statistic
Arthur Getis,Jared Aldstadt +1 more
TL;DR: The two-variable local statistics model (LSM) as discussed by the authors is based on the G i * local statistic, defined as the critical distance beyond which no discernible increase in clustering of high or low values exists.

A geographical solution to scale and aggregation problems in region-building, partitioning and spatial modelling
TL;DR: A geographical solution to the scale and aggregation problems frequently encountered in studies of spatially aggregated data is described and a heuristic procedure is described which may solve this problem and it is demonstrated by reference to an empirical study.

A spatial analysis of gravity flows
TL;DR: In this paper, Curry et al. investigated the association between the spatial distribution of jobs and homes using a spatial regression operator which is interpreted as the impulse response function of a second order difference equation.

Hierarchical Aggregation Procedures for Interaction Data
Ian Masser,Peter J. B. Brown +1 more
TL;DR: In this paper, a hierarchical aggregation procedure for interaction data is considered in relation to the design of spatial systems for operational versions of interaction models, and the application of the intramax procedure is illustrated with reference to the identification of migration subsystems within Greater London and the definition of labour-market areas within Merseyside.
