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…

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)…

The JASP Manual: Now in Spanish and Catalan

We are happy to present two new translations of Dr. Mark Goss-Sampson’s manual Statistical Analysis in JASP: A Guide for Students. Julio Meneses supervised the translation of the manual into Spanish and Catalan. The manual explains how to perform many different types of frequentist analyses in JASP 0.9.2. The translated manuals can be found on the JASP Materials page.

How to Train a Machine Learning Model in JASP: Classification

In this blog post, we show how to train a classification model using JASP’s newly released Machine Learning Module. The goal of a classification task is to predict a categorical target variable based on a (possibly large) set of features/predictors. For instance, based on different concentrations of proteins, a medical specialist might want to classify tissue as “benign” or “malignant”.…

Introducing JASP 0.11: The Machine Learning Module

JASP 0.11 has been released and is now available on our download page. This version adds the Machine Learning module with 13 brand new analyses that can be used for supervised and unsupervised learning. With supervised learning, the goal is to predict a target variable by learning from existing labeled data. The goal of unsupervised learning, on the other hand,…
