How Do I Build a Model? A Starting Guide for New Modellers

August 2, 2026 | Seascapemodels

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...

Analyzing Financial Trends: Kalman Filtering for Gold vs Bitcoin

August 2, 2026 | Selcuk Disci

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 ...

The Future of Programming Looks Like Its Past or Why I build T

August 1, 2026 | Econometrics and Free Software

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...

Little useless-useful R functions – Honest geographical location signposts

August 1, 2026 | tomaztsql

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 ›

‘garchf’: GARCH probabilistic forecasting with package ‘forecast’-style interface (and ‘rugarch’ under the hood)

July 31, 2026 | T. Moudiki

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...

Evaluating LLMs/AI for Media Planning in R

July 31, 2026 | Florian Teschner

LLMs can produce a convincing media recommendation in a few seconds. The more useful question is whether the recommendation is correct: are the reach calculations right, are the assumptions visible, and does the plan fit the brief? I work at Havas Med... [Read more...]

US oil stocks by @ellis2013nz

July 31, 2026 | free range statistics - R

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...

Using ghost text and next edit suggestions to learn agentic coding

July 27, 2026 | Seascapemodels

I’m a big fan of Github Copilots ghost text and next edit suggestions. As a data analyst they give you much more control over the pace and direction of analysis code than a full AI agent. They also let you practice the core skill an agent needs ...

Some useful equations for biological processes

July 23, 2026 | Andrea Onofri

Biological phenomena are often studied by examining how a numerical variable, usually called the response (e.g., the weight or height of an organism), is affected by another variable, usually called the predictor (e.g., time or fertiliser applic...

Babe Ruth: How good was he? Mantle versus Ruth

July 23, 2026 | Jerry Tuttle

As a kid, my baseball hero was Mickey Mantle. In his 18-year Major League career, he amassed tremendous statistics, and surely he was one of the game's all-time greats. When Mantle retired, he was third on...

New Frontier

July 23, 2026 | Stephen Royle

Remember the “AI rat penis” incident at Frontiers in Cell & Developmental Biology? Well, that was two and a half years ago. That’s enough water under the bridge to now check in and see how this incident affected the journal. If we look at how many papers published, we should ...

July 22, 2026 | Joe Roe

controller is an R package for working with controlled vocabularies. It’s first release (v0.1.0) is now available now on CRAN. The package addresses something I find myself doing very often in analysis code: tidying messy and inconsistent terminologi... [Read more...]

HTML and JSON reporting, and smarter scoring for mutation testing in R.

Little useless-useful R functions – Jug solver with Bezout’s Identity

July 21, 2026 | tomaztsql

We all were presented with this problem – water jug problem, which – in the time of Football world cup 2026 – can be translated to any liquid. *hint hint* But the riddle is as logical as mathematical. With mathematics…Read more › [Read more...]

A world still to be mapped: reflections on geocomputation in R: takeaways from the talk and workshop at UseR! 2026

July 20, 2026 | Jakub Nowosad

At useR! 2026 in Warsaw, I contributed to a workshop on Geocomputation with R (July 6, 2026) and gave a keynote entitled A world still to be mapped: reflections on geocomputation in R (July 8, 2026). Both were opportunities to consider what the ...
