JASP

What is JASP?

JASP, or Jeffrey’s Amazing Statistics Program (named in recognition of the Bayesian pioneer Sir Harold Jeffreys), is an open-source program for statistical analysis, supported by the University of Amsterdam. JASP is a free alternative to SPSS that allows you to perform simple and complex analyses in a user-friendly manner. The program is actively being developed and refined, and allows you to conduct both frequentist (classical) and Bayesian analyses.
