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

In her ongoing quest to convince #rstats users to stop invoking the cursed "rm(list=ls())" incantation at the top of their analysis scripts, she has released sessioncheck 0.2 on CRAN. Mostly unchanged, some bug fixes, some new reporting features that are most useful in the regulatory context

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.

And so after a very brief hiatus, version 0.7.0 of "learning statistics with R" exists. Full rebuild in quarto, stylistic fixes, "epilogues from 2026" to comment on how the world changed since original publication, and as an added bonus, no longer misgenders the author learningstatisticswithr.com

New blog post is up. Ever had to manage a bunch of R-based ETL pipelines and wanted a better way to maintain them? I wrote about how {S7} classes and generics can turn a pile of scripts into a more extensible, composable system. #rstats joekirincic.com/posts/this-r-script-could-ve-been-an-s7-class/

i am mortified. i've been writing art code in #rstats for several years now and it was only yesterday that i realised how useful the cauchy distribution is if you want the untidiness in an image to feel naturalistic

Using natural language prompting almost certainly makes LLMs a) need to be larger than they could be, b) less efficient and reliable than they could be, and c) much harder to use than they could be.

New paper with @richarddmorey.bsky.social now out in JASA, where we critically examine p-curve. Below is Richard’s excellent summary of the many poor statistical properties of p-curve (with link to paper). I wanted to add some conceptual issues that we also tackle in the paper.

Paper drop, for anyone interested in #metascience, #statistics, or #metaanalysis! @clintin.bsky.social and I show in a new paper in JASA that the P-curve, a popular forensic meta-analysis method, has deeply undesirable statistical properties. www.tandfonline.com/doi/full/10.... 1/?

Cover page for the manuscript: Morey, R. D., & Davis-Stober, C. P. (2025). On the poor statistical properties of the P-curve meta-analytic procedure. Journal of the American Statistical Association, 1–19. https://doi.org/10.1080/01621459.2025.2544397

Abstract for the paper: The P-curve (Simonsohn, Nelson, & Simmons, 2014; Simonsohn, Simmons, & Nelson, 2015) is a widely-used suite of meta-analytic tests advertised for detecting problems in sets of studies. They are based on nonparametric combinations of p values (e.g., Marden, 1985) across significant (p < .05) studies and are variously claimed to detect “evidential value”, “lack of evidential value”, and “left skew” in p values. We show that these tests do not have the properties ascribed to them. Moreover, they fail basic desiderata for tests, including admissibility and monotonicity. In light of these serious problems, we recommend against the use of the P-curve tests.

it's 3am. i can't sleep. so... art.

abstract generative art in a mostly-dark palette of green, orange, and purple, with one sharp contrasting light tan hue. as with previous examples from this series it has a heart motif in the centre contained within a central box. the textures are grainy and scratchy. this one feels a little gentler than some of the others
