Annotation: Space-time event data are often subject to deficiencies in location accuracy, temporal accuracy, and completeness; this study explores how these failings in the quality of input data may affect the results of global space-time interaction tests.
Abstract: Although previous work has partially investigated the impact of location inaccuracy on the results of these tests, more work remains. The impacts of temporal inaccuracy and incomplete data-reporting on the results of these tests are unexplored. The current study examined the influence of these problems individually and collectively, using a series of simulations. Findings show that even in cases of slight inaccuracy or under-reporting, the consequences on results are potentially severe. Although the study is couched in terms of data inaccuracy, its relevance to situations where inaccuracy is replaced with uncertainty is self-evident. (Publisher abstract)
