Rの怖い話 モデル選択できないGLMM 複数マッチのエラーがでない “sample” surprise なんとなく使っていると痛い目にあうRのデフォルト設定。 モデル選択できないGLMM GLMMで解析する際、lme4::lmer()(あるいはlme4::glmer())を使うことは多い。しかし、これらの関数はデフォルト設定ではモデル選択できない。なぜなら、デフォルトでREML = TRUE(制限付き最尤...

Rにまつわる怖い話をいくつか書いてみました。lmerのデフォルト設定がREML=TRUEとなっており、モデル選択できない使用になっているのに気づかず、やらかしてしまっている論文はかなり多いのでは、、と思ってます。

Watch the mathematics gender gap emerge. The school environment triggers a gender gap in mathematics. Line charts showing test results from all children in France who started school in 2018 reveal the trend. At the start of first year of school boys and girls similar on average with slightly more boys in highest and lowest percentiles. At the start of second year of school the gender gap becomes more exaggerated.

"You Cannot Sound Like GPT": Signs of language discrimination and resistance in computer science publishing LLMs have been celebrated for their potential to help multilingual scientists publish their research. Rather than interpret LLMs as a solution, we hypothesize their adoption can be an indicator of exi...

Analysis of ~80,000 peer reviews in computer science showed (i) papers from Asia/China/TOEFL-required countries receive lower ratings, (ii) this bias slightly reduced post ChatGPT, (iii) reviewers now link ChatGPT "style" with scholar origin, then with the quality of science:

Climatic differences among habitats shape the balance between maximum lifespan and life expectancy in Japanese tree species - Nature Ecology & Evolution Using Japanese forest census data, the authors define potential maximum lifespan and life expectancy for 53 tree species, finding that life expectancy is more sensitive to habitat-associated gradients...

🌳 How long do trees really live?
Our new study in Nature Ecology & Evolution reveals that Japanese trees can have a potential lifespan of ~400 years, but most live only ~80 years. Huge congrats to first author Yuta Kobayashi for this fascinating work! 🎉

Decomposing leaf mass into metabolic and structural components explains divergent patterns of trait variation within and among plant species - Oecologia Across the global flora, interspecific variation in photosynthetic and metabolic rates depends more strongly on leaf area than leaf mass. In contrast, intraspecific variation in these rates is strongl...
