Seriously, who writes this, slaps it, and says that's good that's not going anywhere?
P. S. this is a footnote calling to another footnote.

Here, we start the process towards global random sampling. We can't fully get there, but we can make steps. Our framework:
Cluster random sampling, proportional weighting, BTS, nonresponse bias correction.

It’s usually about 15C when I wake up lately (my landlord won’t let me install a smart thermostat) so the butter is very hard, but I’ve discovered (maybe you all already knew this) that using a vegetable peeler to get thin slices makes cold butter so easy to spread! #lifehacks 🧈

When running an ANOVA (say, 3-groups), F is the omnibus test.
Translated to OLS, 2 dummy variables, the change in R2 is the omnibus test.
BUT, what if analyzing as a Structural Equation Model (in the Figure below)?
Is there something that matches the Omnibus F? Or closely approximates?

I'm starting to see an increase in students wanting group projects to "get to know each other better".
I always thought nothing could be more horrendous in college than a group project.
Now the students yearn for them.

Such "prompt injections" were recently found in submitted academic manuscripts 😱🤯
Here, I empirically test how these injections impact LLM-based peer-review, but also how to spot them and eliminate their effect.

Is classification measurement?
Feels like it is, but classification doesn't require quantitative structure or numbers.
Which would mean measurement doesn't require quantification or numbers.
Which all feels okay, unsure if that leads to contradictions or bigger problems.

![RENEW WAR ON SANTA CLAUS
Asbury Park, N.J. July 8 - War on Santa Claus has been renewed by the School of Methods of the New Jersey Sunday School Teachers' Association in session here. The battle against the children's idol of Christmastide was begun last summer on the ground that the time-honored institution of Kris Kringle takes the minds of the young scholars from the religion [sic] significance of the day.
Last year the teachers sought to have substituted a model Christmas festival, in which the stereopticon played a prominent part and the jolly old saint was banished. It failed Now the teachers have a new scheme of a "living Christmas tree." Teachers and scholars of Sunday schools are to stand in serried ranks upon a circular platform built in tiers, each holding a Christmas tree branch, laden with candles and gifts. At a given signal all are to step down and carry their branches through the audience, distributing the gifts.
