Abstract
A cross-product statistic is used to demonstrate that spatial interaction models are a special case of a general model of spatial autocorrelation. A series of traditional measures of spatial autocorrelation is shown to have a cross-product form. Several interaction models are shown to have a similar form. A general spatial statistic is developed which indicates that the relationship between the two types of models is particularly strong when the focus is on measurements from a single point.

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.

The problems of model specification in one- and two-dimensional stationary random fields are considered, with particular reference to the class of spatial autoregressions, and the role of the autocorrelation function is discussed.
