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.

J'espère que le plupart des gens trouvent au contraire cela rassurant pour l'état de droit
chapeau d'un article du monde:

"En direct, procès Sarkozy-Kadhafi : l’ex-président, condamné à cinq ans de prison avec mandat de dépôt à effet différé, dénonce un jugement « d’une gravité extrême pour l’Etat de droit »
« Cette injustice est un scandale », a réagi l’ex-chef de l’Etat, reconnu coupable d’association de malfaiteurs dans l’affaire du financement libyen. Le tribunal judiciaire de Paris évoque des « faits d’une gravité exceptionnelle » pour justifier l’exécution provisoire de la peine. Cela veut dire que M. Sarkozy n’échappera pas à la prison, même en ayant fait appel."

Trump's Executive Order on Antifa is written such that someone recording masked agents snatching people off the streets, or asking these agents what they're doing, can be deemed a "terrorist."
Section 1.  Antifa as a Terrorist Threat.  Antifa is a militarist, anarchist enterprise that explicitly calls for the overthrow of the United States Government, law enforcement authorities, and our system of law.  It uses illegal means to organize and execute a campaign of violence and terrorism nationwide to accomplish these goals.  This campaign involves coordinated efforts to obstruct enforcement of Federal laws through armed standoffs with law enforcement, organized riots, violent assaults on Immigration and Customs Enforcement and other law enforcement officers, and routine doxing of and other threats against political figures and activists.  Antifa recruits, trains, and radicalizes young Americans to engage in this violence and suppression of political activity, then employs elaborate means and mechanisms to shield the identities of its operatives, conceal its funding sources and operations in an effort to frustrate law enforcement, and recruit additional members.  Individuals associated with and acting on behalf of Antifa further coordinate with other organizations and entities for the purpose of spreading, fomenting, and advancing political violence and suppressing lawful political speech.  This organized effort designed to achieve policy objectives by coercion and intimidation is domestic terrorism.

Gut feeling, I would tend to maximize the available info to impute, so full dataset then subset
