2¹³⁶²⁷⁹⁸⁴¹−1 is the new largest prime discovered to date. Reset the counter! This is a Mersenne prime, which is a Mersenne number that is also prime. A Mersenne number is of the form M_n = 2^n-1. Most of these are not prime. To be prime, n must itself be a prime, but that's not sufficient. 🧪

Approximate Factor Models for Functional Time Series
We propose a novel approximate factor model tailored for analyzing time-dependent curve data. Our model decomposes such data into two distinct components: a low-dimensional predictable factor...

🔥 take: People on the hiring side of academic jobs that post neither salary or tenure guidelines have no right to complain about any aspect of the applications they receive. If you don't want 500 copy-paste applications, don't be one of 200 copy-paste job posts. It's worth your time to fight HR.

The classic "Econometric Theory and Methods" by Davidson and MacKinnon is available for free on their website. Still a great resource for learning and teaching econometrics at the graduate level #statsky #econsky

Great to see so many econtwitter/econsky colleagues out here!! But where are the econometricians and the good old statstwitter community? Any recommendations on who to follow?

I recently experimented with Quarto, the next-gen rmarkdown. It can be used to produce wonderful online lecture sites combining theory with R code. This is a refresher in matrix algebra for my econometrics students:
