We are delighted to announce that registration is now open for the annual Amsterdam workshop on probabilistic modelling for cognitive science. The eighth installment of this workshop takes place August 20-24, 2018. 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 WinBUGS programs…

The JASP Team is excited to announce that registration for our annual two-day Amsterdam workshop is now open. The fourth installment of this workshop takes place on August 27-28, 2018. Program In this two-day workshop, plenary lectures provide the theoretical background of Bayesian statistics and Bayesian hypothesis testing; in addition, practical exercises demonstrate how the JASP program is applied to…

Appalachian State University is located in Boone, North Carolina’s Blue Ridge Mountains. Appalachian enrolls about 18,000 students, has a low student-to-faculty ratio and offers more than 150 undergraduate and graduate majors. It is one of 16 universities in the University of North Carolina system. The Communication Department at Appalachian State is using JASP in its COM 3928 introductory research methods…

The JASP team is happy to announce version 0.8.4. Here’s a select list of new features: A meta-analysis module; A network analysis module; Improved module layout; Stepwise methods for logistic regression; Effect size measures for post-hoc analyses in ANOVA/ANCOVA. In our next post we will take a closer look at the new functionality. For now, enjoy the new version! Like…

We are happy to report that JASP 0.8.3 is now ready for download. Some of the new features have already been discussed in our previous post. Specifically, JASP 0.8.3 now includes logistic regression, hierarchical regression (i.e., the stepwise addition of predictors), a progress bar, and much more. Improvements in 0.8.3 Added logistic regression Added hierarchical regression Added progress bar to…

The JASP team is in the final stages of testing the upcoming version, which is scheduled for release next week. The upcoming version, 0.8.3., contains many new features. My personal favorites: JASP 0.8.3 includes frequentist logistic regression (hat tip to the hmeasure R package for the confusion matrix diagnostics; Anagnostopoulos, Hand, & Adams, 2012). Kudos to Erik-Jan van Kesteren for…

We are happy to report that, just last week, Utrecht University installed JASP on its central IT system, making it instantly available to all of its students and staff. Through the UU platform ‘MyWorkplace’, it is now possible to access JASP anywhere, anytime, and from any device, both on campus and at home. Utrecht University is one of the largest…

Released this week, JASP version 0.8.2.0 brings a number of improvements. For data visualization, the most prominent advance is the extension of the “split-by” functionality (courtesy of JASP team member Erik-Jan van Kesteren). To demonstrate how it works, we plot data from a study conducted at the University of Melbourne in the 1970s, examining the possible relation between hair color…

On particular occasions I find myself almost indifferent about the distinction between frequentist and Bayesian statistics. Usually this happens on weekends, after a few drinks, when my son has fallen asleep, and I am watching my favorite TV show. In those moments of weakness, I find myself thinking “Why all the fuss — often the two paradigms lead to the…

This year we organize two summer workshops in Amsterdam – the first focuses on Bayesian cognitive modeling, and the second focuses on Bayesian statistics with JASP. Before I outline the content of these workshops, let me recount how it was that bitter envy drove me to practical Bayesian modeling. A little over 10 years ago, in a small guest office…
