On a tous vu les images. Et elles sont incroyables. Comme de nombreuses catastrophes naturelles. Le 25 janvier, Niscemi, petite ville sicilienne, s’est ouvert en deux, suite aux pluies torrentielles associées au cyclone Harry, avec une cicatrice de plusieurs kilomètres. On a vu les routes qui s’effondrent, les voitures qui disparaissent, les maisons qui restent suspendues au bord d’un vide. Plus de 1 600 personnes ont été évacuées. Dans l’article du Guardian, on nous rappelle que ce n’est pas la première fois. On nous … <a href=“https://freakonometrics.hypotheses.org/88359" …

Introduction

气候变化与抗菌药物耐药性（AMR）均为全球公共卫生重大挑战。现有证据表明，气温升高和极端天气可通过多种途径影响AMR：包括增加感染性疾病负担从而推高抗菌药物需求、促进病原体适应性进化、加速耐药基因水平转移等。然而，当前研究多呈现生态学相关性，因果机制尚未完全阐明。

This post should have been written in 2024, but my hands were full at that time. I sadly learned from the obituary of Fritz Leisch on the R Project website that he passed away in April 2024.

I didn’t have much direct contact with Fritz, but my career in R would have been very different without his pioneering work on Sweave, which was the main inspiration for me to create knitr later. I used Sweave extensively from 2008 to 2011. It was amazing to me that such a …

Last November, I learned the very sad news from Michael Friendly that John Fox had passed away. That brought my memory back to 2006 when I emailed John for the first time asking for his help on a problem about Structural Equation Models (SEM), which had puzzled me for months. I reached out to him because I had seen an appendix on SEM (freely available on his website) in his book, An R and S-PLUS Companion to Applied Regression. He …
