Spatial aggregation in gravity models:  4.  Generalisations and large-scale applications.
"This paper is concerned with applying and extending a methodology for analysing spatial aggregation in gravity models developed in three earlier papers to a larger scale and hence more realistic example of spatial interaction than has been treated so far."  Seven models are generated and applied to four levels of aggregation of the spatial interaction pattern in Edmonton, Alberta.
