'shiny' Application for Statistical Test Assumption Checking and Guidance

A 'shiny' application to assess statistical assumptions and guide users toward appropriate tests. The app is designed for researchers with minimal statistical training and provides diagnostics, plots, and test recommendations for a wide range of analyses. Many statistical assumptions are implemented using the package 'rstatix' (Kassambara, 2019) and 'performance' (Lüdecke et al., 2021) .
