Hey folks, as news of Watson's demise spreads, please don't set aside his weighty legacy of misogyny and racism. He was truly among the worst of us. www.vox.com/2019/1/15/18...
DNA scientist James Watson has a remarkably long history of sexist, racist public comments
“People say it would be terrible if we made all girls pretty,” he said in 2003. “I think it would be great.”

Do you teach #rstats? Do your students complain about how lame and old-fashioned dplyr is? Don't worry: I have the solution for you: github.com/hadley/genzp....
genzplyr is dplyr, but bussin fr fr no cap.

One week into my new role as an advisor/consultant in data analysis and statistics at the Center of expertise in medical quality registries in the Western Regional Health Authority (Norway). It's quite deliberating the fact that I'm mentally "done" with work when I leave the office around 4PM.

PhD thesis related pt.2: procrastination continues. Taking a theoretical deep dive into beta regression rather than writing about circadian entrainment in the Introduction section💁♀️ Hopefully, I will get the chance to discuss statistics/quant.methods during the defense🤞

PhD thesis related: SO much more fun discussing and criticizing (own) methods rather than working on the Introduction. I guess this is how procrastination manifests. Could have been worse, I could have started making some random R figures for instance💁♀️

Working on the discussion section of the PhD thesis, where I (among other things) discuss ways of estimating intra-individual RT variability. This paper recently came out, featuring one of my co-supervisors: www.nature.com/articles/s41... Graph theory looks like an interesting estimation approach🤓

New blog post! Calculating a correlation is easy enough. But let's say you calculated two of them and they happen to differ. What follows from that? Turns out there are too many moving parts for an easy answer.

What’s in a correlation?
Correlation may not imply causation, but let’s just ignore that for a second. Correlations are standardized effect size metrics and as such have some quirks by design. These are benign enough when you...

Want to visualize the R packages you have used in an analysis, e.g. for a presentation of research results? Recently came across the {hexsession} package made by @liomys.mx, so easy to use and the output looks great hexsession.liomys.mx

Experimentology is out today!!! A group of us wrote a free online textbook for experimental methods, available at experimentology.io - the idea was to integrate open science into all aspects of the experimental workflow from planning to design, analysis, and writing.

"Simpson's gender-equality paradox" surely deserve some award for best title 👑
The gender-equality paradox seems really central to some narrative people have constructed (and successfully sold). I absolutely wouldn't be surprised if it turned out 100% confounding.>
