The thing is, so far I’ve only really talked about methods for setting prior distributions that I don’t particularly care for. Fuck that. Let’s talk about things I like. There is enough negative energy3 in...| Un garçon pas comme les autres (Bayes)
But I got some ground rules I’ve found to be sound rules and you’re not the one I’m exempting. Nonetheless, I confess it’s tempting. – Jenny Toomey sings Franklin Bruno It turns out that I did something a little controversial in last week’s1 post. As these things always go, it wasn’t the thing I was expecting to get push back from, but rather what I thought was a fairly innocuous scaling of the prior.
