Theory and Practice of Bayesian Hypothesis Testing: An Online JASP Workshop

Our annual JASP workshop takes place on August 26–27 and there are still places available. Due to the COVID-19 pandemic, this year’s workshop will again take place online and the fees will be lower than usual. We aim to make use of a number of tools to create a smooth, fun, and interactive learning experience. Below is a summary of…

Workshops: Introduction to Bayesian Hypothesis Testing with JASP

Starting out in Bayesian statistics can be daunting. Learners are confronted with new terms in abundance: prior distribution, posterior distribution, Bayes factor, marginal likelihood, credible interval – just to name a few. If you are all on your own, it can be challenging to get a good grasp of all the important concepts. At JASP, we are committed to increase…

How to Add Functionality to JASP

The JASP programming team has made it easier for new code contributors to add functionality. Specifically, the team has created components in the scripting language qml that make it relatively straightforward to design your own GUI including boxes for the variables, radio buttons, tick boxes, etc. Examples are given in the first part of the JASP YouTube video available here. Associated…

JASP Output Verified With Other Statistical Packages

The only thing worse than statistical software that does not work, is statistical software that appears to work but produces incorrect output. For this reason, verifying the computed results of statistical software is serious business – also for JASP. This is why in July of 2020 we started a systematic verification process. Beginning with the most commonly used frequentist analyses,…

How to Install JASP on Your Chromebook

All Chromebooks that came out in 2019 or later explicitly support Linux and therefore allow JASP to be installed. Certain older models might also have this capability. To find out if your Chromebook supports Linux, go to “Settings” and look for the “Linux (Beta)” option. It should look something like this: If you do not see this entry then your…

How to do Bayesian Linear Regression in JASP – A Case Study on Teaching Statistics

This is a guest post by Tom Faulkenberry (Tarleton State University). Click here to access the supplementary materials. Amid the COVID-19 pandemic, universities have needed to quickly adjust their traditional methods of instruction to allow for maximum flexibility. This means that professors have also had to think critically about how they can best deliver instruction in new formats. Ever the…

Learn Bayes with Binomial Testing in JASP

To facilitate the transition to Bayesian inference we recently created the “Learn Bayes module in JASP” (with support from a grant from the APS Fund for Teaching and Public Understanding of Psychological Science). The goal of this module is to illustrate all steps of Bayesian parameter estimation and testing. In the previous blogpost we outlined the Binomial Estimation analysis, which…

Learn Bayes with Binomial Estimation in JASP

When students are first confronted with Bayesian statistics they have to become familiar with key concepts that differ fundamentally from those that they were taught in frequentist courses. To assist the transition to Bayesian inference we recently created the “Learn Bayes” module in JASP (with support from a grant from the APS Fund for Teaching and Public Understanding of Psychological…

How To Compute Signal Detection Theory Functions in JASP- A Case Study

This is a guest post by Calvin Deans-Browne (UCL) and Henrik Singmann (UCL). Click here to access the supplemental materials. The Setup This article contains an introduction to the different indices measured in the signal detection theory (SDT) framework, a case study to put them into context, and how to compute them in JASP. An Introduction to SDT Indices Signal…
