A Sneak Peek at JASP 0.12

JASP 0.12 will offer important new functionality, including: Bayesian meta-analysis; Classical and Bayesian equivalence testing; Discover distributions; Visual modeling with Flexplot; and various additions to ANOVA. Also, JASP 0.12 offers improved annotation facilities, and our first language other than English — Dutch! (other languages will follow). Just set your language preference to Dutch, and the GUI, the output, and the…

Mediation and Moderation Analysis in JASP

Over the past few years, we’ve found that mediation and moderation analysis are highly requested features. Since version 0.10.1, JASP can do both! This blogpost goes through two introductory examples, showing how mediation and moderation can be performed in JASP. Mediation means that the effect of a variable X on variable Y is (partially) indirect, through the variable M. Moderation…

How to Use JASP: JASP on YouTube

This blogpost provides an overview of the JASP tutorials available on YouTube. We will discuss the available tutorials and highlight some of the videos. First, the video’s by Erin Buchanan, professor in Cognitive Analytics at Harrisburg University of Science and Technology. Erin Buchanan owns the YouTube page ‘Statistics of DOOM’. The channel contains video tutorials for different statistical programs as…

How a Simple Bayesian Test Could Have Rescued a Famous Clinical Trial

One of the features that we have recently added to JASP is a Bayesian “A/B test”, that is, a test for the equality of two binomial proportions. This test is especially popular in the analysis of clinical trial data, where the proportion of medical successes (or failures) from a treatment group is contrasted against those from a control group. The…

Two Workshops on Bayesian Statistics!

We’re excited to announce that we will be organizing two summer workshops in 2020. Similar to previous years, there will be one workshop focused on Bayesian cognitive modeling and one dedicated to Bayesian hypothesis testing in JASP. Unlike previous years, we will also feature Stan in our Bayesian cognitive modeling course! Have you always wanted to know the details of…

JASP Workshop Materials

The JASP team has organized many workshops to teach a broader audience about (Bayesian) statistics with JASP. There has been a lot of interest in the workshop materials and, of course, we are happy to share them. So far, we only responded to requests individually, but due to the growing interest we decided to put a collection of workshop materials…

How to Train a Machine Learning Model in JASP: Clustering

This is a continuation of our series on machine learning methods that have been implemented in JASP (version 0.11 onwards).     In this blog post we train a machine learning model to find clusters within our data set. The goal of a clustering task is to detect structures in the data. To do so, the algorithm needs to (1)…
