📊 Working through ROC-AUC from scratch, then poking at its blind spots — low prevalence, calibration, and finally Decision Curve Analysis. Mostly notes to myself on what I learned (and got confused by) along the way. 🤔📈 Motivations We see ROC-AUC so often with classification models, we know the higher the better, but ...

Introduction Portfolio construction often relies on mean–variance optimization or factor models. Yet, recent research highlights the importance of skewness—the third statistical moment—as a driver of asset returns. Assets with lottery-like payoffs (high positive skewness) tend to be overpriced, while negatively skewed assets are often underpriced. A 66‑page ...

This post estimates potential labor market transition pathways based on the similarity of skills, abilities and knowledge required by occupations. The approach broadly follows Bratanova et al. (2026). Like their research, the considered transition pathways are for workers currently employed as truck drivers. Unlike their approach, we've used a more recent ...

Shiny and Streamlit dashboards depend on a live R or Python process, which makes vanilla deployments slow to load. Observable Framework compiles your data pipeline at build time and ships a static, JavaScript-only site — here's how it works, with a small restaurant-tips dashboard as an example.

One tiny dataset, another rabbit hole 🐇🕳️ In the previous post, I turned 24 Pilot Iroshizuku fountain pen inks into a tiny shop using ggplot2. But while sorting the inks by colour, I started wondering what it would look like if I could rearrang...

Three hundred fifty-three new packages were submitted to CRAN in July. Here are my Top 40 picks in nineteen categories: Causal Inference, Chemistry, Climate Studies, Computational Methods, Ecology, Economics, Econometrics, Genomics, Geomorphomet...

Programmatic Access to Data and Statistics from the World Bank API

Introduction In previous articles, we showed how to test whether two qualitative variables are related thanks to the Chi-square test of independence in R (and how to compute it by hand). Both articles insist on one important limitation: this test requires independent observations. If you have dependent observations (paired samples), ...

We’ve previously extolled the virtues of automating the repetitive chores we encounter, allowing us to focus on the tasks that matter. Three years ago, we posted an example of how to automate the deployment of a Shiny application to shinyapps.io from a GitHub Actions. When a new commit ...
