I’ve now realized that LLMs are to statisticians what WebMD is to physicians.

I will be damned if I allow a bunch of Confederate-waving January 6th apologists give the American people a lecture on flag waving. There is ZERO reason to enter an argument about patriotism with people who still worship traitors to America 150+ years later. They. Are. Breaking. The. Law.

Yes, this administration is dangerous and cruel, but they are also shockingly dim and incompetent. Opportunities are everywhere. Make everything as hard as possible. Resist every demand. Refuse entry without a warrant. Don’t take the buyout. Their problem solving skills are 📉

This article gives a phenomenal overview of the history and evolution of best practices in measurement invariance and differential item functioning -- I can't remember the last time I learned so much reading a single paper, highly recommended! www.tandfonline.com/doi/full/10....

New paper: journals.sagepub.com/doi/pdf/10.1... This was a study I helped with that highlights a little known issue in child maltreatment research. Contamination bias can impact findings when children recruited for the non-maltreated control are or become maltreated during the course of the study
