BREAKING: Friday night massacre underway at CDC. Doznes of "disease detectives," high-level scientists, entire Washington staff and editors of the MMWR (Morbidity and Mortality Weekly Report) have all been RIFed and received the following notice:

Il va renommer Lecornu dans la foulée, on va voir flou.

Lecornu, promettant des changements radicaux propose finalement le même gouvernement, puis jurant que c'était finit pour lui, accepte finalement de continuer 2 jours plus tard.
Le rétablissement de la confiance envers les politiques est en bonne voie

How does you handle this kind of situation for statistics if you are not trained in stat ?

lol, I was toying with gemini to explain a bunch of LLM transformer background knowledge to me since it's way out of my self study depth and for no good reason at all it pulls a diagram of a literal electronics transformer at the end
screenshot showing a large image showing of an electronics transformer works including two wire loops, transformer core, AC power on a primary circuit and lightbulb on the primary circuit, with variables for power and voltage turns, cretited to getty images. Immediately above in text are mathematical formulae and a discussion of the billions of parameters in an LLM transformer model

I didn't know you could write nested loops in R this way

I'm excited to share my new paper with a former student, Tommy Smith. "'This Work Would Not Have Been Possible without...': The Length of Acknowledgments in Sociology Books"

Open Access in @sociusjournal.bsky.social : doi.org/10.1177/2378...
Main figure from the paper. Violin plots showing the length of acknowledgments sections in books by sociologists, broken out by gender, race, sexuality, parents’ education, millennium of author’s PhD, and publisher type.

Just learned: It's so easy to sort strings that are numbers in proper numerical order with the {stringr} #Rstats 📦's `str_sort()` function and numeric = TRUE!!
x <- c("8", "10", "1", "40")
str_sort(x, numeric = TRUE)
[1] "1" "8" "10" "40"

And then you use excel "vibe coding" fonction to analyse the data.
And chatgpt to write the paper.

Can large language models stand in for human participants?
Many social scientists seem to think so, and are already using "silicon samples" in research.

One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.

The threat of analytic flexibility in using large language models to simulate human data: A call to attention
Social scientists are now using large language models to create "silicon samples" - synthetic datasets intended to stand in for human respondents, aimed at revolutionising human subjects research. How...

{tinytable} 0.14.0 for #RStats makes it super easy to draw tables in html, tex, docx, typ, md & png.

There are only a few functions to learn, but don't be fooled! Small 📦s can still be powerful.

Check out the new gallery page for fun case studies.
