🧊 Did your model freeze in time? Let’s bring it back to life!
Join our hands-on workshop “Building Near-Term Iterative Forecasting Workflows” at #TIBS2026 – Aarhus, 6 Jan 2026 🌍
We’ll explore how to turn static predictions into dynamic, self-updating forecasts. @paniw.bsky.social

Heading up to #BES2024 today in Liverpool. Hopefully see lots of you there, and if you are going to be around why not drop in and see some of the group's talks (on #resilience, #seabirds, and #rewilding)

I highlighted this in the paper for ordered beta regression, but I think many don't know this:
you can estimate ordbetareg *just fine* without obs at the bounds (0 or 1).
Maybe your current sample doesn't have 0/1s... but future samples could! Ordbetareg works fine for *any* bounded data.
#rstats

What's even more amusing is that, after sipping from this, the last of the data I'm working with came in. I plotted it up to look at the distributions and....... there are actually no 1 values in it. It's just 0 inflated! Ah well, I'll still drink from and love the mug!
