sparrpowR: Power Analysis to Detect Spatial Relative Risk Clusters
sparrpowR is an open source, R-based software package that provides power calculations for the local statistic of the spatial relative risk function. Using user-defined parameters, sparrpowR generates spatially clustered point-level data and detects spatial clusters with high statistical power within two groups. Further functionality is available to overlay power calculation results on user-provided Geographic Information Systems.
sparrpowR provides investigators with an easy-to-implement method to calculate the statistical power of spatial clusters, which aids in the design of more efficient studies.
