Below I describe how to set up the fully integrated AI in JASP. All of the individual steps are straightforward. If you get lost or if anything is unclear, you can simply ask your favorite LLM for advice, and it will help you out. Let’s go! Step 1: Activate the AI in the JASP Preferences Menu Open JASP. From the…

TL;DR The upcoming JASP version (due to appear this week) will bring a fully integrated AI. Use an API key to hook up your own LLM and take advantage of its ability to propose and conduct new analyses, annotate the results inside JASP, and explain statistical concepts you may have forgotten. On Friday June 26th, Henrik Godmann and I presented…

In less than a week, on Friday June 26th, JASP will be presented at the “Praxistag Qualität” at the Fraunhofer Institute for Manufacturing Engineering and Automation (IPA) in Stuttgart. This is an event targeted towards industries in southern Germany. The presentations are in German, but luckily several JASP team members are German, and in this case Henrik Godmann will impress…

Named after Italian economist Vilfredo Pareto, the Pareto principle states that 20% of the causes (the “vital few”) are reasonsible for 80% of the consequences. Translated to the context of quality control, this means that most problems (e.g., delays, products that are out of spec, etc.) can be attributed to a small number of underlying causes. Identifying those causes (and…

Six Sigma training companies are starting to offer their courses with JASP. This is great, but it presents an immediate challenge in the sense that training materials and books need to be translated to JASP. In the past few weeks, we have spoken to two training companies in the Netherlands, and we have decided to help them “JASPify” their materials.…

Because of René’s initiative, foresight, and expertise, JASP now features a first-rate quality control…

Information hidden in raw data can be revealed most easily by means of statistical visualization techniques (“always plot your data”). To demonstrate I will now analyze the duration of reign (in years) for each of the 148 rulers of ancient Egypt and Nubia (“pharaohs”). Data are taken from https://www.metmuseum.org/toah/hd/phar/hd_phar.htm. High priests and monarchs who ruled less than one year are…

A week ago I started a small quality control project where I measured twenty “1 kg” Albert Heijn (AH) potato bags in order to assess whether or not AH is systematically underfilling them, as some social media posts had implied. Surely you have mulled over what the results would look like, and it is now time for the big reveal.…

A few days ago I announced a small quality control project where I would measure twenty “1 kg” Albert Heijn (AH) potato bags to assess whether or not AH is systematically underfilling them, as some social media posts had implied. I have now completed the measurements and I know what the data show. Before revealing the results, however, I would…

Recent social media posts have shocked Dutch society to its core, prompting public outrage and cries for tribunals. What had happened? Well, a few customers of the largest supermarket chain in the Netherlands (the Albert Heijn or AH for short) were interested to learn whether the “1 kg” bag of potatoes (i.e., about 2.2 pounds) really contains 1 kg of…
