Name for how to compare probablistic models?
I'm sure there is a whole lot of material on how to do this but I don't know what it is called.

Suppose I've got some probablistic models (e.g. weather forecasts that say 20% or 40% likely rain on Tuesday and then it does or doesn't rain that day) and I want to check a bunch of predictions vs results and determine which is best. (So one prediction is slightly off for a lot of days and another is usually right but occasionally really off, determine which is better.)

What do I look up to study on this kind of mathematical question? Thank you. RJFJR (talk) 03:49, 29 March 2021 (UTC)
