Osteoporosis Is Common and Undertreated Prior to Total Joint Arthroplasty

The Journal of Arthroplasty, 2019
Osteoporosis is common in total joint arthroplasty (TJA) patients and likely contributes to the increasing incidence of periprosthetic fracture. Despite this, the prevalence of osteoporosis in patients undergoing elective TJA is inadequately studied. We hypothesize that preoperative osteoporosis is underrecognized and undertreated in the TJA population.

Representing Bayesian games without a common prior

International Joint Conference on Autonomous Agents and Multiagent Systems, 2010
Game-theoretic analyses of multi-agent systems typically assume that all agents have full knowledge of everyone's possible moves, information sets and utilities for each outcome. Bayesian games relax this assumption by allowing agents to have different "types," representing different beliefs about the game being played, and to have uncertainty over ...

PEOPLE WITH COMMON PRIORS CAN AGREE TO DISAGREE

The Review of Symbolic Logic, 2015
AbstractRobert Aumann presents hisAgreement Theoremas thekey conditional: “if two people have the same priors and their posteriors for an eventAare common knowledge, then these posteriors are equal” (Aumann, 1976, p. 1236). This paper focuses on four assumptions which are used in Aumann’s proof but are not explicit in the key conditional: (1) that ...

Finite Order Implications of Common Priors [PDF]

Econometrica, 2003
I characterize the implications of the common prior assumption for finite orders of beliefs about beliefs at a state and show that in finite models, the only such implications are those stemming from the weaker assumption of a common support. More precisely, given any finite N and any finite partitions model where priors have the same support, there is

A Note on Common Prior [PDF]

, 2005
Harsányi introduced the concept of type space in an intuitive way. Later Heifetz and Samet formalized it. Harsányi used conditional probabilities to model the beliefs of the players, Heifetz and Samet avoided using conditional probabilities formally.

Common priors for generalized type spaces [PDF]

, 2011
The notion of common prior is well-understood and widely-used in the incomplete information games literature. For ordinary type spaces the common prior is defined. Pinter and Udvari (2011) introduce the notion of generalized type space. Generalized type spaces are models for various bonded rationality issues, for finite belief hierarchies, unawareness ...

Common Priors and Markov Chains

1996
The type function of an agent, in a type space, associates with each state a probability distribution on the type space. Thus, a type function can be considered as a Markov chain on the state space. A common prior for the space turns out to be a probability distribution which is invariant under the type functions of all agents.

Common Priors For Like-Minded Agents [PDF]

, 2003
Two agents are like-minded when their beliefs are equal once conditioned on knowledge of both of their types. Assuming the existence of an outside observer that is commonly known to be likeminded and uninformative about the insiders, we derive the existence of a common prior among the insiders, with the outsiders beliefs (appropriately conditioned ...
