Compositional data (proportions that sum to 1) behave in ways standard models aren’t built for

I walk through why Dirichlet regression is often the right tool & what extra insight it gives, using a real example of eyetracking

#statstab #480 Criticism as asynchronous collaboration

Thoughts: Gelman considers this different from a commentary or critique. Interesting. Thoughts?

Two weeks ago, Dr. Sinuhé Sánchez visited us to present his research findings in the frame of our #UNAM-#TUBraunschweig 🇲🇽 🤝 🇩🇪 collaboration on #reanalysis data with a special focus on #hurricanes & subsequent applications as reservoir management optimization 🌊. It was a pleasure to host him!

Paper alert🌧 Working in a region without high-resolution #precipitation data, and #reanalysis products show low performance? We used a rainfall generator and estimated the parameters from #ERA5-Land & #COSMO-REA6 data! #ProudSupervisor #hydrology #water

Don't you just love seeing the #ARGO network getting going?

Our colleagues Christina Radtke, Hannes Müller-Thomy, Tobias Langmann and Henning Müller are currently in Mexico at @UNAM_MX 🇲🇽 for a research project on #reanalysis products focusing on #hurricanes. Check out the recorded talk: https://youtu.be/AfcNuYseXcE
We are excited about upcoming collaborations!

Hello from Reading! Our colleague Janna is currently at the NWP SAF Workshop on Satellite Observations of the Earth System Interfaces (https://events.ecmwf.int/event/420/). Exciting insights and discussions about how we can exploit #satellite #observations for numerical weather #predictions and #reanalysis even better!
NWP SAF Workshop on Satellite Observations of the Earth System Interfaces

HD photoOverviewInterface observations refer to observations that are sensitive to multiple Earth system components, including atmosphere, land, sea ice, snow, and the ocean. They are key for Numerical Weather Prediction (NWP) and reanalysis. In a coupled data assimilation framework, used in Earth system approaches, satellite-sensed interface observations have the unique potential to simultaneously constrain the various Earth system components, providing consistent initial and boundary...

Nighttime #stats question: When conducting a meta-analysis, which tests would you put under Robustness and which under Sensitivity? And what is your definition of each?
