Yep - I had a number of panic emails yesterday asking for recertification of biosketches. Good times.

Oh it does! For me it’s about three hours of prep for one hour of lecture. And that’s in the in-class lecturing! It’s probably longer for developing an online course.

I’ve never turned mine. I like to keep people guessing. When will I reply? In 5 minutes? A week? It’s unknowable.

The main analysis is mean change on the treated? The control group feels slighted.

yes this is a classic! My favorite part is when the manager says he gets "better regressions" when he does this. Oh I bet he does!

Our faculty lounge also has a microwave and full sized fridge. We cleverly named it the mail room to hide it from state officials

I told a story at my lab meeting today about the time I met John Cougar Mellencamp…and none of my grad students had heard of him. I must be nearing the end of my days…

It feels like all of our graduate students are defending their dissertations this spring...and I am on all of their committees.

That's it! Makes sense to me now. Thanks - hope you've been well!

In IRT modeling, shouldn't the 1PL model have one more degree of freedom than the Rasch model? In the 1PL I am estimating a common discrimination parameter where the Rasch model sets it to 1. But the mirt package in R is saying they have the same number of parameters.

OK. I guess I'll whip up some simulations to see how much violating the assumption of equilibrium and stationarity has on the model.

Chris Schatschneider @schotz.bsky.social · 07/08/2025
Ok. I've convinced myself that the RI-CLPM model is not appropriate for modeling constructs that are systematically growing/changing over time. These data don't meet the assumptions of the model. But I keep seeing it getting recommended for developmental studies. Am I missing something?

I love springing this fact on the first year grad students in my class just to see their reaction.

Chris Schatschneider @schotz.bsky.social · 25/07/2025
Genius. If I could convince people of the utility of Degrees of Non-Freedom I've got a number of under-identified models that I think would work great.

Chris Schatschneider @schotz.bsky.social · 25/07/2025
I may not know much, but I know a model with -5 degrees of freedom is not going to fly.

Thanks Jens! I appreciate that. It was a crazy surreal experience.

I was teaching when the active shooter warning came. I can tell you the one thing I was not prepared for. Trying to determine if we should stay in the classroom and start building barricades vs. evacuating the classroom for a more defensible position. Was it safe to let my students in the hallway??

I am here! I’ve been reading some pretty interesting discussions. But I think they could be improved with the occasional snark post :)

Has someone made a shit-poster starter pack? A list of accounts that post snarky comments, random puns, or lighthearted statistical modeling jokes?

Yea I worry about that too. How many researchers undervalue data and reporting accuracy? I don’t know but I’m guessing it’s way too many.

Chris Schatschneider @schotz.bsky.social · 19/12/2023
What I have done is gone to journals like PLOS where the data is shared (at least theoretically), found some articles that used ANOVA then I re-analyze the data and map it back to the paper

Chris Schatschneider @schotz.bsky.social · 13/11/2023
I believe the problem is trying to disentangle growth from fluctuations from time point to time point due to the other variable. If something is at equilibrium it would mean we can disregard actual growth as a confound. At least that’s how I understand the issue.
