New paper on how to calculate a multistate death distribution! What's that, you ask? Usually, we plot a death distribution by age at death. But age at death is the sum of our time spent in different states. If we split time between being healthy or not, then the distribution is multistate (1/3)

And actually--Comet Pizza was a page out of a playbook that started with daycare decades before.
In 1983, a California mom accused her son's childcare provider of subjecting children to Satanic rituals--like flushing them down toilets into secret basements where they were then filmed for porn. 1/🧵

Trump guys are about to Comet Pizza every third daycare center because they think they are all fronts for Somali money laundering. They're only doing this near cities with progressive mayors. This is straight up Government by LibsOfTikTok.

NSF is about to dismantle NCAR at Russell Vought's direction to protect the fossil fuel industry. It's hard to communicate just how much NCAR does, so let's take a look: I've never worked at NCAR, and I've worked with NCAR researchers once ever. What scientific discoveries has NCAR made possible? 👇

Why are there so many ways to compute a frequentist interval for a proportion? Because the sample space is discrete, coverage can be garbage without adjustment. The Agresti-Coull interval ("score" below) is really a Bayes interval with a weak prior, has good freq coverage! >
