Jeff Rouder @jeffrouder.bsky.social · 03/11/2025I think the less packages you use in R, the better. Right now, ggplot2 3.5.0 is incompatible with ggtern. Boo! 130
Jeff Rouder @jeffrouder.bsky.social · 22/10/2025Today, it was announced that all UCI faculty will have to take a mandatory training course on ethics and conflict of interest. Today, it was reported Trump is demanding $230M from the Justice Dept. led by his crony appointees. 110
Jeff Rouder @jeffrouder.bsky.social · 20/10/2025ok, i am back here. it’s been a while, but i miss academic twitter. Todays subject: Canvas is out. It is affecting my course as we had an assignment due last night and now I am dealing with many, many emails from students. 030

Jeff Rouder @jeffrouder.bsky.social · 12/02/2025I am reading the most insightful, scholarly, fun text I have read in a long while. It is “The Myth of Statistical Inference” by Michael C. Acree. I cant put it down. Fascinating analysis; charming writing style. Wish I had the author’s email if he still gets email. 010
Jeff Rouder @jeffrouder.bsky.social · 11/02/2025Anyone ever read, “Boswell, J. (1986). The awful truth about publishing: Why they always reject your manuscript— and what you can do about it. New York: Warner Books.” Sounds like my kind of book. 000
Jeff Rouder @jeffrouder.bsky.social · 11/02/2025Q? Have you transitioned from base R or ggplot2 graphics to python Seaborn? Are you happier? Is it easier? Can ppl with experience in both comment? Thinking about going from R to python and Seaborn would be foundational in my workflow for visualization. Thx. 200
Jeff Rouder @jeffrouder.bsky.social · 22/01/2025I am gratefully in the service of my students. I am gratefully in the service of my students. I am gratefully in the service of my students. If I repeat it enough, will i detest grading any less? 030
Jeff Rouder @jeffrouder.bsky.social · 17/12/2024Q? Do you teach looking up values in t/F/z tables? Did you? If so, when did you stop? For me, it was around 2005. So, up to 20 years ago, I taught students how to use these tables. Does anyone still teach this? 030
Jeff Rouder @jeffrouder.bsky.social · 05/12/2024Yes, I do wonder what percentage of our natural gas bill is for seasoning cast iron pans. 041
Jeff Rouder @jeffrouder.bsky.social · 04/12/2024Do you use lavaan? If so, do you run across negative variances or correlations out of range on occassion (Heywood cases). What do you do? 441
Jeff Rouder @jeffrouder.bsky.social · 04/12/2024Hello All, First time here in a while. I used to love twitter, and I left when Elon bought it. I hope to see this platform become that vibrant exchange of ideas for me that twitter was. 060
Jeff Rouder @jeffrouder.bsky.social · 05/11/2024Damn, are you all as nervous as I am. Can't really concentrate on anything today. Just waiting for polls to close. 030
Jeff Rouder @jeffrouder.bsky.social · 03/11/2024I am currently prepping my course for the week. There is some chance that come Wednesday I am so traumatized and intellectually paralyzed by the election results that the only words I can stammer in class are, "What The Fuck Is Wrong With This Country." At least I will have good slides then. 140
Jeff Rouder @jeffrouder.bsky.social · 16/10/2024Ok, we all know facts on chatGPT is not reliable. And, the vast majority of facts we find on Google, say "what is the annual rainfall in Tel Aviv," is reliable. Except, now, with new Google AI, it rains 57" a year in Tel Aviv. It became a rain forest. 1/2 260
Jeff Rouder @jeffrouder.bsky.social · 14/10/2024You know, even after decades in the field and scores of papers an grants rejected, you would think it wouldn't bug me. Oh, quite the contrary, getting a paper rejected still upsets me greatly. 030
Jeff Rouder @jeffrouder.bsky.social · 25/09/2024I have been social media averse lately. But I miss my old twitter feed greatly. So, I am in the market for more friends and enemies, especially those that post and argue (thoughtfully preferred, but I am not too picky). There is a lot to complain about! 100
Jeff Rouder @jeffrouder.bsky.social · 13/09/2024Picking a fight w/ bels and decibels. We are better off without them. Why, because there is no physical unit log(cm) or log(kg). We just say "log-multiplier" and "tenth-log-multiplier." When you say a multiplier, the multiple has no unit and the need for a physical referent is obvious. Thoughts? 000
Jeff Rouder @jeffrouder.bsky.social · 09/06/2024Distributions with full support of reals and a natural shift parameterization: normal, gumbel, ex-gaussian. Can you think of others? 010
Jeff Rouder @jeffrouder.bsky.social · 02/06/2024Do you publish in English-language journals where English is not your first language? What is your experience vis-a-vis language issues. Do you find diction/grammar corrections helpful or annoying? Should we native-English speakers correct infelicities (or not) when reviewing manuscripts? 100

Jeff Rouder @jeffrouder.bsky.social · 29/04/2024Hi All, I decided to engage in academic twitter stuff again after a very long hiatus. Been busy learning factor models. Here is a crazy fun fact: If variables explain 5% of the variance in one anther, but a common factor between them explains 25% of the variance in each! Variance paradox! 020
Jeff Rouder @jeffrouder.bsky.social · 21/11/2023Had a blast at Psychonomics 23. If you want to learn more about reliability as a signal-to-noise ratio, the accepted version of the preprint is at osf.io/preprints/ps... 051
