Abstract
AbstractA statistical procedure for the analysis of patterns of spatial distribution of artifacts over occupation areas is outlined. This procedure envisions 3 steps: the testing for non-randomness of spatial concentrations in the distribution of each class of artifacts, the reorganization of the data so as to best reflect such concentrations in the analysis of intercorrelation among those artifact classes which exhibit significant spatial patterning, and finally the analysis of spatial intercorrelations among these artifact classes and the definition of clusters of classes of artifacts based on their similarity of distribution over the area concerned. A new statistical method called dimensional analysis of variance is presented as a method with which to begin this series of steps. Dimensional analysis of variance works with data in the form of counts per grid unit, thus making it applicable in many archaeological situations for which no other statistical methods are available for spatial analysis. The procedure of spatial analysis, based on dimensional analysis of variance, is illustrated with the analysis of a preceramic occupation floor in a small cave in the valley of Oaxaca, Mexico.
