I didn't change the default correct answer to the actually correct answer for 2 items on my multiple choice Psych Measurement final when I built it so there were a couple students who ended up doing better than I did on the test lol #AcademicSky #SchoolPsych #ClinicalPsych #Psychometrics

Google AI is useless. This made me laugh.

As if we weren't already in full blown constitutional crisis. Might as well throw the damn thing in a paper shredder at this point.

It’s a good thing Congress isn’t alive to see this

Do you use behavior rating scales that offer a general total score and subscale scores?🚨SPOILER!!!🚨You probably shouldn't be interpreting most of those. Come join and learn how to tell which scores are uniquely interpretable and which are wasting your time! #schoolpsych #clinicalpsych #psychometrics

CLARIFICATION : The Trevor Project's hotline will still be live. But basically this means LGBTQ people can no longer be connected to it through the US national 988 suicide prevention hotline. They will need to be contacted DIRECTLY So spread this around They can be texted. They can be called.

There are only 4 useful decisions for peer reviewed journals. Reject R & R Major revision (goes back out for full review) R & R Minor revision (reviewed only by AE and editor) Accept Everything else is just confusing and unhelpful.

It came up, for highly scientific reasons, during yesterday's Data Science Lunch in my department that one can estimate the speed of light using a microwave oven and marshmallows. I've successfully done this experiment in my own home. Here's a nice video explaining. www.youtube.com/watch?v=HwRE...

- Twin Peaks - 30 Rock - Mad Men - Curb Your Enthusiasm - Better Call Saul* *MAYBE swap for Sopranos given the day but Kim Wexler is the best written female character in TV history and I would miss her

This Thursday I will give a talk on (causal) mediation analysis -- happy to have finally worked out what I want to tell people. And happy to pilot a new mode of slide sharing: just putting them on my website (juliarohrer.com/resources/)

Gave the final today in my doc stats class. One student brought these cookies to share and I've never been so proud. #RStats #AcademicSky

Do you have a favorite empirical example of a situation in which there is a (documented) lack of measurement invariance? Send them all my way 😊!

This is a *key* new paper in the world of school mental health interventions A very large trial (N=6388) testing a universal CBT-based app for adolescent depression (13-14y) No effects found (on depression, anxiety, distress or insomnia) (🧵) mentalhealth.bmj.com/content/28/1...

My first #TidyTuesday: I really enjoyed exploring the Pixar dataset and getting more comfortable working in R with new data. Enjoyed @andrew.heiss.phd's program evaluation course this semester. Excited to keep building my R skills over the summer in #dataviz! #rstats

‼️ New paper @ Child Development discussing why it is inappropriate to use traditional common factor models to model adverse childhood experienced (ACEs) and other stressor inventories ‼️ Read full (brief) paper at srcd.onlinelibrary.wiley.com/doi/full/10.... @srcdorg.bsky.social #PsychSciSky 1/9

Hey, just a quiet reminder: it’s not true that people get more conservative as they age. *Populations* get more conservative as they age because poor and marginalized people die sooner. nymag.com/intelligence...

📚😅🎉 Yay!! I just submitted the complete manuscript of my upcoming book to the publisher! Learn to easily and clearly interpret (almost) any stats model w/ R or Python. Simple ideas, consistent workflow, powerful tools, detailed case studies. Read it for free @ marginaleffects.com #RStats #PyData

After seeing FiveThirtyEights implementation of this idea (thank you @andrew.heiss.phd for sharing), I've been working on a medicine themed p-hacking simulator called Placebo playground: medicines.charlwood.xyz#phacking #pharmsky #healtheconomics #medsky #pharmacy 1/3 🧵

Just one more scale bro, please bro 🙏 we just need to make one more scale bro then it will fix everything!

I’ve long used FiveThirtyEight’s interactive “Hack Your Way To Scientific Glory” to illustrate the idea of p-hacking when I teach statistics. But ABC/Disney killed the site earlier this month :( So I made my own with #rstats and Observable and #QuartoPub ! stats.andrewheiss.com/hack-your-way/

Who has an academic website they’re proud of? I’m especially interested in websites by grad students, and in websites built with Quarto. I’ll be offering a local workshop on building a website with Quarto, and I’m keen to give my audience examples. #rstats

Hey beautiful causal inference people! I was invited to give a workshop on mediation analysis, ca. 90-120 min. What would you cover? Thinking both in terms of topics to be covered (e.g., mediator-outcome confounding, sensitivity analyses?) & practical implementations (R packages worth introducing)

Predictor -> Oracle Prediction -> Prophecy Outcome -> Destiny

Think this is a good way of talking about the disconnect

Here are some cool animations I made a couple years ago for teaching DAG-based causal inference Confounding!

Friends, I have written you a book on forensic metascience. It is free. You can have it. Happy St. Valentine's Day. If you wish to give me a gift back, you can use it to cause trouble - the greatest gift of all. open.substack.com/pub/jamescla...

An important avenue for securing our data

Aw yeah, nice text demonstrating a coherent approach to generalized LMs that DOES NOT start with logistic regression for a change

Good example of how untangling temporal precedence helps clarify potential intervention points and can refute "common sense" but wrong causal beliefs

A little good news among the bleakness this morning

People wanting to do structural path modeling bc ~pretty graph~ when regular regression or just straight up correlations are what's needed

Calling school psychologists! #schoolpsych

Would love to see splines become more common in school mental health risk modeling where it's common to dichotomize risk status bc that's how people are used to interpreting those scores. This offers a nice compromise, keeping the continuum intact. #schoolpsych #stats #youthmentalhealth

Welp, looks like my quant class is getting a new extra credit assignment this semester

Does anyone have any suggestions for books by women authors on the topics of data engineering, analytics, or visualization? (We already have a lot of books around general data topics, but specifically want more technical ones, too.)

Been trying to find satisfying approaches to address item redundancy and like a gift from the gods here we are

Syllabus update time. What are your favorite articles on consultation in psychology? Any area (instructional, behavioral, mental health, systems), but with youth/school populations would be ideal. #schoolpsych #psych #CBTworks
