Cross-Validation From Scratch and a Surprise at n=100

August 4, 2026 | r on Everyday Is A School Day

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...

R GUI Comparison Update

August 4, 2026 | Bob Muenchen

Graphical user interfaces for the R language are easy to use and getting more powerful all the time.

With so many detailed reviews of Graphical User Interfaces (GUIs) for R ...

Centering a map projection on the mapped region

August 4, 2026 | A.M. Barbosa

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 →

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 ›

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...]

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 ...
