Foundations for Bayesian Updating

submitted by: dougramsey
We provide a simple characterization of updating rules that can be rationalized as Bayesian. Namely, we consider a general setting in which an agent observes finite sequences of signals and reports probabilistic predictions on the underlying state of the world. We study when such predictions are consistent with Bayesian updating, i.e., when does there exist some theory about the signal generation process that would be consistent with the agent behaving as a Bayesian updater. We show that the...

The Importance of Marine Picoeukaryotes and the Search for Lost Time

submitted by: dougramsey
Unicellular eukaryotes are responsible for a massive amount of photosynthetic carbon fixation in marine systems. The smallest among these fall within the “pico” size fraction (<2 micrometers in diameter), are broadly distributed – from coastal to open-ocean environments – and are highly diverse. Picoeukaryotes contribute a significant proportion of the biomass and primary production within this size fraction, often rivaling their cyanobacterial counterparts Prochlorococcus and...
