JASP (Jeffrey's Amazing Statistics Program) is a cross-platform statistical analysis software that provides a GUI for conducting both Bayesian and frequentist statistical analyses. Built with the Qt framework using a C++/QML hybrid architecture, it offers point-and-click interface for statistical tests, data import/export capabilities for multiple formats (CSV, Excel, SPSS, etc.), integration with R for computations, and a modular system for extending functionality. The application features computed columns, data filtering, variable transformations, OSF cloud integration, encryption for file security, and result export to HTML/PDF.
