Quick data science / stats question: my feature of interest is 98% missing values with a NMAR structure. Can I just assume it's missing-at-random to estimate a summary statistic? Kthxbye!https://twitter.com/zeynep/status/1324150678642692096 …

Maybe even worse. It’s also x NMAR and y MAR, and x+y are 98. Now let’s see that summary statistic. Illusion of weightability. (Is that a word?).

I kinda suspect that polarizing elections are likely to exacerbate structured non-response, and even if you guess the direction of the effect, the magnitude is still inherently unknowable just by polling. Just when you most want them to be accurate...

They aren’t shy, as much as low trust. Can’t fix just with demographics.https://twitter.com/davidshor/status/1318934721552912390 …

I've been wrong about plenty of things! I think that public polls are *probably* repeating the state-level error pattern that they saw in 2016, but I really could be totally wrong! Predicting polling error is hard! https://twitter.com/davidshor/status/1258756577877725190 …
