Archaeology has a long running research tradition in the study of spatial data (Hodder and Orton 1976, Rossignol and Wandsnider 1992, Bevan and Lake 2013), an endeavour that encouraged the borrowing of statistical methods from other disciplines. Many of these techniques have been adapted to answer existing questions, others fostered new lines of enquiry. Nonetheless the fi eld of spatio-temporal analysis remains surprisingly under-developed in archaeology. Despite theoretical debates on the notion of time (e.g., Bailey 1983, Gamble 1987, Murray 1999, Holdaway and Wandsnider 2008, etc.) and a large number of studies in chronometry (e.g., Buck and Millard 2003, Lyman and O’Brein 2006), spatio-temporal statistics did not experience the same fl ourishing of ideas observed in spatial statistics and GIS-led analyses.
