@profandyfield.com Is it true that the R book is really coming out on Jan. 1? Is there somewhere we can get a table of contents?

Applied quantitative methodologist at Michigan State University. To statisticians, I'm an early literacy researcher. To early literacy researchers, I'm a statistician.
Many thanks to MSU for issuing policies critical for my syllabus less than a week before the start of classes. After I finished the syllabus.

No, because it's hearsay. And not an exception to hearsay. Or it's an exception to an exception. But not an exception to an exception to an exception.

This analysis was supposed to be easy. F*** you, data.
It finally happened. I have a student in my grad stats course whose advisor was once my student in the same grad stats course.
Language people: my trivia team had a rhyming question where the answer was Towel Howl. We had a debate about whether those words actually rhyme. Thoughts?
Delete everything. If it's important enough, they'll email again. Note: Despite the brilliance of this strategy, I have never been able to implement it.

A Likert scale is always some form of Disagree to Agree rating scale. It is a type of rating scale, not synonymous with rating scale. This is a hill I will not die on, because I have given up and have nothing left but to scream into the Bluesky void.
Underappreciated fact: „When the entire population is measured there is no need to perform a hypothesis test. After all, there is no pop. to generalize to. When data from the entire pop. has been collected the pop. effect size is known, and there is no confidence interval to compute.“
How much different do two samples need to be for factorial in invariance to be meaningful validity evidence? For example, randomly splitting a sample in two and finding factorial invariance is definitely not meaningful validity evidence.
I taught a lecture on IRT today, and I have to say that even after 25 years in the field, I don't really get it. In the absence of a causal theory of the response process, what can IRT really say about measurement and validity?
Always entertaining to discover what autocaptioning thinks I said in my recorded lecture. Today, I am doing a Principle Commodes Analysis.
I changed my email signature to "Best Linear Unbiased Wishes, Ryan" months ago and I just finally got the second comment from a recipient. Perhaps I'm emailing with the wrong kind of people.
All of my manuscripts will now have a Concept of Analytical Plan section.

I'm teaching today, so I'm wearing my fancy sneakers. Still getting inspiration from my sabbatical with @schotz.bsky.social five years ago.
Looking forward to finding out how much I disagree with them.

I'll be teaching a course on measurement focused on internal structure validation methods (FA, IRT, Rasch). Need to update syllabus and readings. Any recommendations? Example syllabi?

My students made brownies because "it's the only way we could make sure Ryan showed up." This is absolutely not true and absolutely true at the same time.
This is a really clear and simple explanation. I'm sharing it with my students!
