#PhDone #PhDSky - I have successfully defended my PhD thesis yesterday. I’m incredibly grateful to everyone who supported me along the way, especially to @profandyfield.bsky.social who’s been a wonderful supervisor and a mentor throughout the process.

🧵 A brief thread on the topic 👇

Some already do, and it's quite a trip trying to write a plain-language summary about heteroscedasticity.

This post went from "Oh fun!" to heart palpitations really fast.

I often end up using super long object names because a_meaningful_name_is_always_better, we have the tab-autocomplete, it's *fine*.

The idea that we have to "encourage responsible AI usage" is a core part of the inevitability narrative driving the institutional adoption that makes people think it's worth trying out.

it contributes to the very problem it supposedly tries to solve. we can't let it go unchallenged.

I did hear a bit doing the traditional "Open access publishing is now so expensive no-one can afford to do it". And I mostly want to stand up and scream Green.

I seem to spend my life wanting to stand up and scream green.

Glad someone found a use for it(: the accepted version has the same key messages but includes a more rigorous literature search strategy and clearer technical definitions.

Our review paper with @profandyfield.com just got accepted to PeerJ 🎉 osf.io/preprints/ps...

We review OLS models and their assumptions, discuss statistical practice, and offer some practical tips on how to use robust methods with preregistration to reduce unnecessary analytic degrees of freedom.

In psychology, CIs are pretty common so I guess it depends on the discipline.

I love raincloud plots - it's a nice way to combine raw data distributions + summary stats in one plot. Here's an R package with some examples: github.com/njudd/ggrain

I'd use confidence intervals because they're more useful for inference 🤷. But if both SD and SEM are relevant and needed, why not plot both? You could try something like a raincloud plot with the SD displayed on the "cloud" and SEM around the mean.

Why even have a brain, any ideas, any ability to express them, any kind of communication with other people, any desire to solve problems or invent anything, any reason to learn, any use for your eyes or your heart, or any reason to teach or create

From NYT article about the increasing use of AI in the classroom: “Writing is one of the most challenging tasks for students, which is why it is so tempting for some to ask A.I. to do it for them. In turn, A.I. can be useful for teachers who would like to assign more writing, but are limited in their time to grade it.”

I do descriptive stats first with psych students - show what kind of measures can be used to summarise data (central tendency and dispersion), then show how to plot them and how _not to_ plot them.

Just above The Long Man of Wilmington (walked from Eastbourne). Devil's Dyke is on the list next time we get weather like this.

Post a photo you took with no context to bring some zen to the timeline.

View of the South Downs, sunlit, with blue skies above. Photo taken from the top of the hill while standing on downward-leading path. There's a fence following the path on its right side. Green fields and small villages can be seen in the distance.

Parallelization just landed in the dev version of purrr: purrr.tidyverse.org/dev/referenc...

Really pleased that the mirai framework makes this possible.

Huge credit to the tidyverse maintainers @hadley.nz @lionelhenry.bsky.social and @davisvaughan.bsky.social !

What's the moment of luck that's had the biggest impact for your academic career? For me, it was how I wouldn't have gotten a PhD fellowship if it wasn't for the 1st-ranked person declining, which meant that I was awarded the fellowship as 2nd-ranked applicant. That was my last shot at a PhD.
