tfw linkedin informs you that literally the stupidest academic colleague you ever had the misfortune to work with has now transformed himself into the worst kind of AI grifter, despite possessing absolutely no technical skills of any kind

reading an old blog post written by a trans woman describing a form of abuse that is very familiar. she documents the reasons why you're never permitted to disclose that this form of abuse even happens. and lo and behold i am not even going to link to it because that would disclose too much :/

It's always bothered me that I make so many data visualisations in #rstats, but the graphics devices that make that happen have remained a mystery to me. So I set out to teach myself how to write one of these things. Not at all convinced this was the best use of my time, tbh. Oh well.

How to build a custom R graphics device – Notes from a data witch

Did I need to write a graphics device to output plots to an HTML canvas? No I did not. Did anyone ask for this? Oh hells no. Ah, but did I have fun? Hahahahahahahaha. No

i asked claude to spell check my prose and am amused that it quite primly informed me that it was leaving my profanity as-is, considering it a style choice in fairness it was but i'm almost hurt. hon this one is terribly tame. in australia six fucks for a blog post is considered the queens english

honestly cannot decide if i think this is cute or if i totally hate it. it's just a little throwaway art system i put together or a blog post i'm writing about graphics devices, but i can't make up my mind about it

kind of looks like a hand drawn circuitry board (sort of, not really) with dots and rectangles wired up messily in an approximately rectangular way. the palette is pink, yellow, grey, and black against a dark grey background

The paper itself mildly interesting: the effect size is large enough that it matters (surprising zero trans women), but the key result is an interaction between disclosure and passing-status. When both are present, the hiring discrimination is substantially higher than predicted by an additive model

this might be a controversial take but i don't think it's a good idea to create a simulated torture chamber for AI agents. even if the machines aren't capable of experiencing suffering, humans can absolutely be trained to enjoy torturing others. best not to go down that path. i would think

i have never loved the "you are valid" trans affirmation. it's always struck me as trite and basically content-free. the fact that anti-trans organisations can use the exact same text to mean the exact opposite thing kind of suggests that i was right about that. it's inherently meaningless

cozy@bimbotheory.bsky.social · 5d ago

Notice how this fully anti-trans detransition therapy rhetoric is so functionally similar to the "you're valid no matter what, you don't have to transition to be trans" rhetoric that we have all inculcated ourselves to?

the feeling of artistic liberation when you pull the code out of the clutches of the machine and make it your own. kind of looking forward to exploring what i can do with this now

A small followup to this post. The appendix contains links for the data and data-generating script, but perhaps more usefully, also links to a more carefully worked out version of the cut_quantile() function than the simple one I used in the post minis.djnavarro.net/minicuts/

Appendix - The toy data set is available for download as exposure_response_data.csv, and the script that generates it is also available as simulate_data.R. - I’ve also put together a more carefully worked version of the cut_quantile() function that allows user control over the quantile-estimation method used to define break points, and three options for tie-handling behaviour at the break points, including the two traditional quantile/cut approaches (ties always fall upwards and ties always fall downwards), along with a third “ntile-like” approach that allows tie-splitting to produce more even bins, but only permits ties to be broken randomly (with built-in seed control), never by row order. It automatically detects when the data set cannot support the number of requested bins, and provides informative warnings and error messages as needed.The script itself is avaliable as minicuts.R and it has a brief accompanying vignette documenting what it does.

Please, I am begging you. Do not use dplyr::ntile() in any serious statistical analysis in which you want to group continuous observation into quantile-based bins. Despite the name it doesn't actually do that, and the thing it actually does is very dangerous when accuracy matter. #rstats

The title is a little pointed, but I am very serious here. Academics, medical researchers, and other organisations should not collect data on birth sex. It is rarely relevant, and it almost always leads to privacy violations for transgender people. Please share. I would like people to read this one.

Separating sex and gender is statistical malpractice – Notes from a data witch

Statisticians and academics in Australia should ignore the terrible advice of most LGBTIQA+ organisations and read this post instead. The 2020 ABS standard is almost never the correct way to collect d...
