That’s a tough lesson to learn.

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

You’re TV famous!!

People still give you paper copies?!? That’s kinda awesome

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!

One of my absolute favorites

This gives me life! So does this meme :)

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.

Yikes

Agree to disagree.

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.

But not so sad that it would stop her from eating them :)

It was and continues to be absolutely brutal for Ed Science researchers

I’m pretty sure you want to keep that under your hat until AFTER they hire you :)

Under Pressure duet. I thought the David Bowie parts would be easier to sing. They were not.

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

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.

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.

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??

Everything outside is just covered in a fine yellow blanket of allergens…
