Save the Date – Annual Workshops

We’re excited to announce that we will be organizing two summer workshops in 2023. Similar to previous years, there will be one workshop focused on Bayesian cognitive modeling and one dedicated to Bayesian hypothesis testing in JASP. Save the date and come join us in Amsterdam this July. Note that the Annual Meeting of the Society for Mathematical Psychology is…

Bayesian Repeated-Measures ANOVA: An Updated Methodology Implemented in JASP

This post is a teaser for van den Bergh, D., Wagenmakers, E., & Aust, F. (2022). Bayesian Repeated-Measures ANOVA: An Updated Methodology Implemented in JASP. Preprint available on PsyArXiv: https://psyarxiv.com/fb8zn/ In JASP 0.16.3 we changed the default Bayesian repeated-measures ANOVA. It is important to understand this change as it may affect the results, bringing them more in line with the…

Generalized Linear Models (GLM) in JASP

It took a while, but finally, the frequentist Generalized Linear Model (GLM) has become available in JASP, as part of the Regression module! In this blog post, we give you a quick introduction to the idea behind GLM and the full functionality of this new JASP sub-module. We also show you how you can conduct a binomial regression analysis using…

Meta-Analysis of Prediction Model Performance

It is highly recommended to evaluate the performance of prediction models across different study populations, settings, or locations since good performance is essential for proper decision making regarding patients’ health (Debray et al., 2015). When multiple estimates of prediction model performance are available (e.g. from the published literature), meta-analysis may help to obtain a summary estimate and investigate the presence…

How to Predict with Machine Learning Models in JASP: Classification

This blog post will demonstrate how a machine learning model trained in JASP can be used to generate predictions for new data. The procedure we follow is standardized for all the supervised machine learning analyses in JASP, so the demonstration here generalizes to all of them. Please note that we use the latest version of JASP (version 0.16.2). For our…

Introducing JASP 0.16.2: Performance Improvements, Apple Silicon, and Bug Fixes

JASP has been updated! This is a maintenance release that contains the following improvements: Performance improvements on both Mac and Windows resulting from upgrades to our development framework (Qt 6.2, R 4.1.3) There is a new build for Apple Silicon (e.g., M1 iMacs and Macbooks) that makes use of Apple’s new chipset resulting in a significant speed up. The installation…

Latent Growth Curve Modeling (LGCM) in JASP

‘How can we model the form of change in an outcome as time passes by?’, ‘Which statistical technique helps us to describe individual growth trajectory’s over time?’, ‘Can individual differences in an initial state and in change over time be analyzed?’ These questions are of importance to researchers who examine developmental, longitudinal, or consecutive measurements across multiple occasions. What solves…
