🔍Why is C2C needed?
Through C2C:
✅Student and families can make informed decisions about their future goals.
✅State leaders can access info to support policy decisions. 👇

You've heard of the many analysts projects, right?
Scholars give the same dataset/question to a bunch of researchers & they still get different answers.
Why is that?
Data cleaning!
This is consistent with Gelman's "garden of forking paths." Small coding decisions often drive results.

If you are a macroeconomist, I would say lock in your estimates of the output gap now and potential gdp now. I believe this is going to be the most important question in macroeconomic policy for next 12 months.

Trump's tariffs are a massive tax that YOU will pay.
That means higher prices and serious pain for families and small businesses across our country.
Repost if you agree Republicans need to join Democrats and vote to END the chaos & REVERSE these reckless tariffs.

Very useful thread. This also a helpful reminder for folks who are working with coarse statistical tables and historical documents as well.
If you have research dependent on these data here is my suggestion
1/N
Big picture:
Create a dataset of cell means (cells must be big enough to pass disclosure)
- load these cell means into many, many tables & put through review
-These cell means can then be used in OLS - which runs on means
1/N

Research with restricted-use data is more precise, powerful, and relevant. Faculty and staff will be working through the weekend to answer important research questions before we no longer can. This is not normal, necessary, or efficient.

Simulation studies are common in psychometrics. We are trying to make them more relevant to practice by increasing their connection to empirical data. Feedback welcome!
