many meetings are truly useless. truly. but once in a while, as i listen to a conversation, someone makes a comment--sometimes it's a throwaway or filler--and it becomes the rosetta stone for a project i am working on.

I’m making a pledge to not submit to journals that force you to meet their idiosyncratic formatting rules for initial submissions. Happy to comply on any revisions, just not first try.

totally unrelated, but the feeling of saying, "yeah, i can do that stats thing you're asking about" when you're not sure that you really can do it. but then it turns out that, yes, you really CAN. 🥰

tensor product splines are super cool and i'm kind of in love.
that's it. that's the entire post.

Should these be called ‘secretly informative’ priors?
The default prior for the intercept in both {rstanarm} and {brms} are very wide.
Counterintuitively - being on the logit scale, this is actually translates to a **strong** prior that p(y=1) is near 1 or near 0.
Always check your priors!

Item 7,543 in the never ending list of r functions I wish I had known about sooner.
Much cleaner syntax inside functions that fit models across multiple outcomes (which happens a lot in my work).

nice paper on partial least squares discriminant analysis &potential limitations.
lovely sentence from the conclusion section:
"The obvious conclusion from our experiments is that it is a terrible idea to use PLS-DA blindly with all data sets."

I was just in a coffee shop in a college town. At least half the laptops were open to ChatGPT windows. I mean, I know many people use LLMs as a replacement for google search. But omg, this feels…worrisome.

I love when good things, like mgcv, get even better! #rstats
A new release of the mgcv #RStats 📦 is out on CRAN and Simon Wood (U Edinburgh) has added some significant new features despite the small bump in version number:
🌟 scasm() for estimating GAMs with shape constrained smooths. Can be used with any family & smoothness selection is via the EFS method

Dear Apple engineers. Can you please stop setting ‘logit’ to autocorrect to legit, leftist, login, or really anything else? When I say logit, I mean logit!

This also makes me (sadly) wonder if prior-hacking is the Bayesian equivalent of p-hacking?

Man, I’ve written some ugly code in the past. But this lumbering beast of regex i just vomited to filter thru 2500 rows of free text is an unholy masterpiece to behold. And no, I will not be sharing. #rstats

Without an explicit SESOI, readers will apply implicit SESOIs (as happened here) and the discussion becomes unnecessarily confused. SESOIs have nothing to do with sample size, but "with large N, people suddenly become aware of the matter" (@dingdingpeng.the100.ci). Thanks for coming to my TED talk.

I ❤️ science.
"Because science rejects claims to truth based on authority and depends on the criticism of established ideas, it is the enemy of autocracy. Because scientific knowledge is tentative and provisional, it is the enemy of dogma. "

@hadley.nz in case you’re taking suggestions for new #tidyverse verbs, may I suggest ‘yoink()’?
i don’t yet know what it does. But whatever that action is, I’d for sure use it *all the time!*

Ever discovered a new function in an r package and been like, man that’s so useful. It must be new or else I’ve had known about it?
I advise against looking up when it was added to said package, unless you’re looking for a blow to your #rstats self-esteem.
