My students are out collecting air quality data around campus. Excited for what they’ll find 👀 This year I purchased 20 additional low cost sensors & if anything, I’m hoping the practice of collecting their own data is fun. #AirBeamMini

I actually learned about simulation-based model assessment as a tool for any framework first. I’m surprised it’s not used more broadly in non-Bayesian settings.

Some questions have come up as to why we set early deadlines for workshops & abstracts. Here’s why: Visas! It can take time to apply for a visa, find funding to attend, etc. The more time we can give, the better.
