One method applicable to the examination of spatial point patterns of
disease, the calculation of K-functions, is presented. The technique i
s used to determine the degree of clustering exhibited by the residual
s from a spatially referenced legit model constructed to ascertain the
factors influencing the likelihood of death in a road traffic acciden
t. This was done to test if there was some systematic geographical fac
tor influencing outcome not adequately controlled for in the model. K-
functions are extremely versatile, overcoming many of the problems of
incorporating the notion of scale associated with traditional methods
of spatial autocorrelation. Recently software has become available whi
ch allows their calculation in an easy to use Geographical Information
System style environment. This study illustrates the relevance of the
method, not only to the analysis of data on mortality and morbidity,
but also to the examination of the residuals from any spatial regressi
on.
