@gelliottmorris There are many things you can do to make your model more robust out of sample. But you can't actually actually make an out-of-sample prediction if you know the result, and data science curriculum that teaches people otherwise is wrong and instills a lot of bad habits. — PolitiTweet.org

The New York coronavirus numbers in Cuomo's presser are quite good across the board (at least under the circumstances). But I'd be careful: we've seen lots of places where the numbers come in lighter on Sat/Sun/Mon and heavier Tues/Wed/Thurs. Wait for Tuesday, in other words. — PolitiTweet.org
