We are delighted to announce that registration is now open for the annual Amsterdam workshop on probabilistic modelling for cognitive science. The tenth instalment of this workshop takes place August 22–26, 2022. Program In this workshop, plenary lectures provide the theoretical background of Bayesian statistics, and practical computer exercises teach participants how to use the popular JAGS and Stan programs…

The JASP Team is excited to announce that registration for our annual two-day hybrid Amsterdam workshop is now open. The workshop will be happening both on-site and via Zoom and it takes place on August 29–30, 2022. Program In this two-day workshop, plenary lectures provide the theoretical background of Bayesian statistics and Bayesian hypothesis testing; in addition, practical exercises demonstrate…

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…

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…

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…

‘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…

We are happy to announce that JASP 0.16.1 has been released and is now available on our download page. JASP 0.16.1 contains the following new features and improvements: JASP is now available in French (incomplete). The Machine Learning module has been expanded so that you can now perform (1) Support Vector Machine regression and classification analyses, and (2) Decision Tree…

Researchers often have questions about inter-relationships between observed variables (indicators) and latent variables (factors). The Multiple Indicators and Multiple Causes (MIMIC) model is one of the models to quench the thirst for such questions! The latest JASP release provides MIMIC models as part of the SEM module. This tutorial introduces the idea of MIMIC models and, with a simple example,…

Many research questions in the social and behavioral sciences rely on between-group comparisons of scores on scales from questionnaires. But how do we know that the questionnaire measures the same thing across different groups? Such comparisons require measurement invariance to be appropriate. Multi-group-Modeling, an analytical approach that belongs to the class of Structural Equation Modeling (SEM), provides the toolbox that…

There are multiple statistical tests concerning a single parameter of interest such as t-test or a binomial test of proportions. Those tests can be performed with summary statistics that completely describe the observed data. In this new analysis, we extend the “Summary Statistics” module with a “General Bayesian Tests” analysis that allows us to evaluate the evidence in favor of…
