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

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 trouble with ‘ntile()’ – Notes from a data witch
Please, please, please do not use ‘dplyr::ntile()’ in an analysis that will be submitted to a regulatory agency. It’s secretly an ill-conceived SQL tool that doesn’t do what you probably want it to, a...

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.
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...

Today is the anniversary of the Box-Cox power transform. #OTD 1964 George Box & David R Cox read their paper “An Analysis of Transformations” at the RSS meeting. It describes methods for reducing nonnormality of errors in a linear model. The paper began with their names then found the topic. 1/3
