Crazy days! While helping w/ 🐦ringing @OssFaunAsinara, my FIRST PAPER went OUT at @RSECJournal! 🤩🎉

with Mattia Brambilla, @DavideScridel et al.💕 we investigated #snowfinch thermoregulatory behaviour and microhabitat selection from space. Get a look! https://t.co/Jpf73ZrMHx

Key Takeaways from “Regression Modeling Strategies” by Frank Harrell (@f2harrell)

A must-read for anyone working with predictive modeling. Here’s what you need to know:

Plan your model with clear goals—whether prediction, effect estimation, or hypothesis testing. Avoid arbitrary categorization of continuous variables, as it leads to information loss and reduced statistical power.

Use flexible techniques like restricted cubic splines to relax linearity assumptions while maintaining interpretability. Avoid stepwise selection, which often results in overfitting. Instead, rely on penalized regression methods such as ridge or elastic net.

Handle missing data effectively through multiple imputation rather than case deletion. Reduce dimensionality using redundancy analysis, variable clustering, or principal component analysis to make models more efficient and interpretable.

Validate models rigorously using bootstrap resampling rather than splitting data into arbitrary training and testing sets. Focus on calibration and discrimination metrics like concordance indices to assess predictive performance.

Communicate results clearly with visualization tools such as diagnostic plots and nomograms. Simplify models thoughtfully through approximations rather than haphazardly dropping predictors.

This book combines theoretical depth, practical advice, and reproducible R code, making it essential for statisticians, data scientists, and researchers in fields like biostatistics and machine learning.

[Wouter Vansteelant @WMGVs]

Decided to call it an early weekend after a series of super intense days. The gods, it seems, approved and granted me spectacular conditions to watch the enormous flocks of Ruff, Dunlin, Golden Plover and Lapwing currently at Blaugerzen. 🤩🤩
