In our series Interview With A Team Member, we aim to introduce the people behind the JASP-project. Today we are interviewing Tim de Jong, one of our software developers! Tim de Jong is a software developer at JASP. He is responsible for improving the R analyses and enriching the Bayesian ANOVA and t-tests. To contact Tim, you can send him…

Jim Berger is one of the most prominent Bayesian statisticians alive today. Berger combines strong mathematical ability with a deep knowledge about the foundations of Bayesian inference; for decades Berger has contributed valuable new insights and procedures, and is partly responsible for the increased prominence of objective Bayesian inference. Moreover, Jim Berger has the rare gift of being able to…

The 6th edition of the APA style manual (American Psychological Association, 2010) states the following on the topic of reporting p-values: “When reporting p values, report exact p values (e.g., p = .031) to two or three decimal places. However, report p values less than .001 as p < .001. The tradition of reporting p values in the form p…

In 34 short chapters, Prof. Robert Matthews provides an engaging tour of practically relevant topics whose treatment benefits from a little “common sense expressed in numbers”. These topics include lotteries, insurance, casinos, and the law. This book distinguishes itself favorably from others in its genre. The chapters are well written and relatively concise, making the work ideally suited for readers…

This year we organize two summer workshops in Amsterdam – the first focuses on Bayesian cognitive modeling, and the second focuses on Bayesian statistics with JASP. Before I outline the content of these workshops, let me recount how it was that bitter envy drove me to practical Bayesian modeling. A little over 10 years ago, in a small guest office…

Our new introduction video demonstrates the basic functionality of JASP. In just under 5 minutes, the demo discusses data editing, the user-friendly GUI, the presence of both classical and Bayesian analyses, the ways in which JASP facilitates statistical transparency, and more. The video was voiced by Alexander Etz. Editing and animations were made by Alexandra Sarafoglou and Tim Draws. The…

For its frequentist analyses, JASP offers familiar output: effect sizes, confidence intervals, and p-values. However, JASP also provides a more mysterious measure: the "Vovk-Sellke maximum p-ratio" or VS-MPR.
