R-bloggers

This post asks how institutions should be conceptualized and analyzed: can the rule of law (and other institutions) sensibly be examined one at a time, or do they need to be treated as parts of an interdependent system? The post Institutions Are a Package Deal: What a Correlation Can’t ...

This is another short, simple blog post building a chart I am going to be updating regularly as part of monitoring the impact of the slow-burn fuel crisis caused by the USA war with Iran. I have a page on this website with a few charts on the fuel cri...

I realized this week that I won’t be hiring a GIS focused research assistant the same way as I used to. Claude Code is just too good at GIS in R now. I guess this happened around the release of Opus 4.7. I just hadn’t really pushed the coding ...

Announcing the Bioconductor Student-ECR Council From an idea that hatched during the EuroBioC2026 Birds of a Feather session, we are super excited to announce the formation of the Student-ECR Council! As a newly established Council, we aim...

SAS is almost 50 years old. It predates the web, and it predates most of the open source tools data teams reach for today. While old, it is not obsolete. SAS remains central to clinical research, banking, insurance and other regulated industries,...

Textbooks say LOOCV has the lowest bias but highest variance compared to 10 and 5-fold. Coded a K-Fold CV from scratch for learning to test that on simulated data 🔍📊 — and at n=1000 it holds up. At n=100? Not so much. 🤔 The above image was generated...

Graphical user interfaces for the R language are easy to use and getting more powerful all the time. Here is my updated comparison of jamovi, JASP, BlueSky Statistics (free & Pro), Rattle, RKWard, R-Instat, R AnalyticFlow, and R Commander. With so many detailed reviews of Graphical User Interfaces (GUIs) for R ...

The PROJ format for defining Coordinate Reference Systems (CRS) is becoming deprecated, as PROJ strings cannot accurately store modern datum transformations, coordinate epoch information, or complex axis order rules. However, that format is much easier and more practical for humans … Continue reading →

After an extended beta period, JAGS 5.0.0 is now available. The release is more of a process than a single event, but we have started by uploading the source tarball and the Windows installer to SourceForge. The macOS installer will … Continue reading →

I’ve put together a short guide: How Do I Build a Model? A starting guide for new modellers. It’s free, online, and aimed squarely at the graduate student who has a research question and is staring at a blank script wondering where to even begin...

In their paper “A Synchronized Multi‑IMU Wearable System for Tracking of Joint‑Angles in Sports Motion Analysis” (arXiv:2607.26027v1), Samarasekera and colleagues set out to solve a very practical problem: how to reliably measure joint angles in dynamic sports movements using wearable IMUs. Their goal was to design a ...

This is a post based on two other posts I wrote for LinkedIn. It has become quite long. AI Won’t Save People From Work They Never Thought to Automate I’m a fairly optimistic person, but when it comes to AI adoption and how it will be gene...

We have all seen colourful signposts with great cities and their distances – how far each is from this current standpoint. And fundamental question is, how correct these distances are? Or even, one should ask, how honest a particular signpost…Read more ›

The package garchf wraps the extensive GARCH modeling machinery in rugarch behind a forecast-style interface, so that GARCH-based forecasts can be produced, plotted, and evaluated with the same conventions used throughout the forecast ecosystem (in the...

Like many people I have been keeping track of the slow-burn fuel crisis arising from the war in Iran, its possible expansion to the Red Sea, and exacerbation from the ongoing war between Russia and Ukraine. The latter seems to have reached a stage wher...
