Excerpt
In this context we define spatial analysis to mean Statistical Inference which takes into account spatial data, including but not limited to spatial exploratory data analysis. Groups in a Cluster randomised trial (CRT) are often defined geographically, giving spatial structure to the data. Taking account of the spatial aspects in the design and analysis of such a trial is important as it may influence results. In addition, the hierarchical structure imposed by the design should be adjusted for in the analysis. Therefore selecting software for spatial analysis of CRTs necessitates the capacity to accommodate for both spatial and clustering effects. …
