A Game-Theoretic Analysis of Updating Sets of Probabilities
Peter D. Grunwald, Joseph Y. Halpern
We consider how an agent should update her uncertainty when it is represented by a set P of probability distributions and the agent observes that a random variable X takes on value…
When Ignorance is Bliss
Peter D. Grunwald, Joseph Y. Halpern
It is commonly-accepted wisdom that more information is better, and that information should never be ignored. Here we argue, using both a Bayesian and a non-Bayesian analysis, that…
Updating Probabilities
Peter D. Grunwald, Joseph Y. Halpern
As examples such as the Monty Hall puzzle show, applying conditioning to update a probability distribution on a ``naive space', which does not take into account the protocol used,…
Making Decisions Using Sets of Probabilities: Updating, Time Consistency, and Calibration
Peter D Grunwald, Joseph Y Halpern
We consider how an agent should update her beliefs when her beliefs are represented by a set P of probability distributions, given that the agent makes decisions using the minimax…
