A probabilistic framework for assessing spatio-temporal point patterns in the archaeological record

Enrico R. Crema, Andrew Bevan, Mark W. Lake
2010 Journal of Archaeological Science  
Introduction The application of spatial analysis in archaeology has in most cases relied upon methods adopted from neighbouring disciplines such as geography, ecology and epidemiology.  ...  Typically, point pattern analysis assumes that: 1) the spatial pattern in question can be reasonably simplified as a series of zero--dimensional events (points) located in a Euclidean space; 2) the observed  ...  The output in this case will represent the density of a point process in probabilistic terms, which in turn can be used as the input data for a wide range of tools grouped under the label of spatial time  ...
