Projections in Model Space: Multi-model Inference Beyond Model Averaging
A reviewer of the manuscript challenged us to do two things. First, to move beyond simple likelihood ratio examples and show how evidential ideas are used in the practice of science. And, second to solve some deep problem in ecology using this framework. To answer the first challenge, we discuss information criteria differences as a natural extension of the likelihood ratio that overcomes many ...
متن کاملClimate Projections Using Bayesian Model Averaging and Space-Time Dependence
Projections of future climatic changes are a key input to the design of climate change mitigation and adaptation strategies. Current climate change projections are deeply uncertain. This uncertainty stems from several factors, including parametric and structural uncertainties. One common approach to characterize and, if possible, reduce these uncertainties is to confront (calibrate in a broad s...
متن کاملIterative Averaging of Entropic Projections for Solving Stochastic Convex Feasibility Problems
The problem considered in this paper is that of finding a point which is common to almost all the members of a measurable family of closed convex subsets of R++, provided that such a point exists. The main results show that this problem can be solved by an iterative method essentially based on averaging at each step the Bregman projections with respect to f (x) =∑n i=1 xi · ln xi of the current...
متن کاملA note on lifting projections
Suppose $pi:mathcal{A}rightarrow mathcal{B}$ is a surjective unital $ast$-homomorphism between C*-algebras $mathcal{A}$ and $mathcal{B}$, and $0leq aleq1$ with $ain mathcal{A}$. We give a sufficient condition that ensures there is a proection $pin mathcal{A}$ such that $pi left( pright) =pi left( aright) $. An easy consequence is a result of [L. G. Brown and G. k. Pedersen, C*-algebras of real...
متن کاملIdeal Projections and forcing Projections
It is well known that saturation of ideals is closely related to the “antichain-catching” phenomenon from Foreman-Magidor-Shelah [10]. We consider several antichain-catching properties that are weaker than saturation, and prove: (1) If I is a normal ideal on ω2 which satisfies stationary antichain catching, then there is an inner model with a Woodin cardinal; (2) For any n ∈ ω, it is consistent...
