Three-quarters of eggs produced in the United Kingdom are free-range— Growing up in the United Kingdom in the 1990s and early 2000s, almost all the eggs in our supermarket came from battery hens, those raised in small wire enclosures.

Really nice to see this published! I was one of the peer reviewers and it's so refreshing to see some nicely done SoTL research. I'm the kind of reviewer who checks the data and code for reproducibility and everything was pristine. journals.sagepub.com/doi/10.1177/...

Bayesians: does anyone (@solomonkurz.bsky.social maybe?) have a good resource for how to set priors for beginners? Such as what kind of information in past papers you can use to inform your choices? I found this but any resources welcome! svmiller.com/blog/2021/02...

The @ukrepro.bsky.social just published a new primer on computational reproducibility, authored by the CR special interest group, including yours truly! I hope it's useful for introducing people to the concept and convincing resource-holders to fund efforts to improve it. zenodo.org/records/1923...

James Bartlett@bartlettje.bsky.social · 9mo ago

After sitting on some revisions for months, I've made some major changes to one of my preprints. I outline an assessment approach which embeds the concepts of reproducibility and replicability while students are demonstrating their analysis skills. osf.io/preprints/os...

I’m sorry, you can do what now…?!

Mattan S. Ben-Shachar@mattansb.msbstats.info · 7mo ago

You can specify relative position in ggplot with I(x) I(y). E.g. annotate("text", x = I(.5), y = I(.5), label = "hello!") will place the text in the middle of the plot. This, combined with alignment arguments is like 87% of the magic for me.

Too many significance tests!! Made this little graphic for my #stats class, showing the various kinds of (N)HST and how interpreting confidence intervals can replace all of them. Made with #rstats #ggplot (duh)
