it's wild that R, the ubiquitous statistical computing language, was co-created by a Māori prof (Ross Ihaka) — and yet the vast majority of scientists who use R don't know

this is like inventing the toaster. possibly the largest impact of a single member of an indigenous community on modern science

I’m sorry what, 75% called strike accuracy?! That’s unbelievably bad for any game, let alone the playoffs.

Oh man what a game. The Tigers really grinded that out. Props.

Tigers-Mariners is just maximum intensity right now 😐

Utter abominations of at-bats by Perez and Torkelson. The Tigers are just so frustrating to watch right now.

Brady West @bradytwest.bsky.social · 8d

Utterly pathetic and unacceptable not to score in that situation. Win this game or not.

Yet more evidence against the highly questionable idea of silicon sampling.

AI-generated ‘participants’ can lead social science experiments astray, study finds

Data produced by “silicon samples” depends on researchers’ exact choice of models, prompts, and settings

Wait…you mean the inability of the Tigers to hit anything wasn’t automatically cured by the magic “It’s The Playoffs Now!” switch? Weird. 🙄

I think that everyone on this thread would benefit from reading this article:

The central question is whether the weights are informative about the model parameters that you are trying to estimate.

Researchers apply sampling weights to take account of unequal sample selection probabilities and to frame coverage errors and nonresponses. If researchers do not weight when appropriate, they risk hav...

An excellent piece, especially for those of you who may not work with survey weights every day.

Danielle Navarro @djnavarro.net · 12d

A few words on survey weights, why I'm embarrassed to have forgotten to take them into account in the past, and how I got lucky because I personally didn't get burned. Not a mistake I intend to repeat in the future

I gave a talk at ISR yesterday on declining response rates in surveys, and why we should not automatically assume that this means our survey estimates will be subject to nonresponse bias. Here is the recording for anyone interested! Thanks again to ISR Insights. 🙏

As good as the Lions were last night, the Tigers have been that bad or worse for a month straight. This team-wide collapse has been nothing short of astonishing.

Brady West @bradytwest.bsky.social · 17d

What a game from the Lions! All three phases! LFG! #FDTF
