spatiAlert is a Shiny app for detecting spatial hotspots of childhood undervaccination using the Getis-Ord Gi* statistic. All analysis runs on your own machine, so data never leaves your computer. Upload school- or tract-level data, choose spatial weights (queen, rook, or KNN consensus), and generate maps, tables, and manuscript-ready methods text.
