I feel like we are in a golden age of AI right now, like when google first appeared and you could get your search results without adverts. How long before AI results start incorporating ads?

Yeah so there's no way anyone is coming here for World Cup or Olympics. if you can bag up the son of one of the most famous boxers to ever live, you can do that to anyone.
Mexican boxer Julio Cesar Chavez Jr., who fought Jake Paul on Saturday in CA, has been arrested by U.S. immigration officers and is being processed for expedited removal from the country, the Department of Homeland Security said in a statement Thursday.

protip for Gen Z working with older colleagues: if discussing data or studies which occurred entirely after the year 2000, you can refer to them as *21st Century*. It will sound futuristic and sci-fi to anyone who grew up on Buck Rogers, Flash Gordon (i.e., Gen X, Boomers) - very impressive!

Add this to my reading list: “For “random intercept” models, adding the group-level averages of all included variables as regressors (or a variety of equivalent procedures such as group-wise centering) relieves the bias otherwise induced by this regularization”
A paper I find extremely interesting on the equivalence between fixed effects models and "tweaked" random effects models:

Spoke to Jen a few weeks ago because I am also trying to pivot out of academia. Can confirm Jen is a great person to help you focus on what’s important (to anyone else who is in a similar situation). She would be a great asset to any community building enterprise
A bit of an update thread: I resigned from my academic position at UNSW a few months ago now and have been taking a break to rest, reflect, and work out what I want the next half of my career to look like.

In this post, I explain different approaches for solving linear regression in R: directly, using QR, singular value and Cholesky decompositions, and do some benchmarking for comparison with in-built approaches.

A lawsuit in Rockland County, NY, alleges election irregularities in the 2024 Presidential and Senate races.
The plaintiffs claim statistical anomalies and uncounted votes.
But do these claims hold up?

The quarto-preprint extension v0.16 (github.com/mvuorre/quar...) now enables full-width content in two-column #quartopub #typst documents (and more!; via github.com/christopherk...). Hope this makes Quarto a bit more useful for writing well-typeset reproducible #rstats manuscripts 💙

One of my pet peeves with dplyr verbs in R is filter(). It should remove the rows which meet the condition(s). What is the most readable way to remove rows which meet a joint condition? e.g., remove rows where col_a == "x" & col_b > y? #rstats

TIL the difference between interaction and effect modification: "[An] interaction is the effect of 2 interventions whereas effect modification is the effect of one intervention varying across strata of a second variable." I think this means things like sex cannot interact with other variables...
Thanks to everybody who chimed in!
I arrived at the conclusion that (1) there's a lot of interesting stuff about interactions and (2) the figure I was looking for does not exist.
So, I made it myself! Here's a simple illustration of how to control for confounding in interactions:>
