Inconsistency measuring over multisets of formulas

2018

International audience; Measuring Inconsistency in Information : The concept of measuring inconsistency in information was developed by John Grant in a 1978 paper in the context of first-order logic. For more than 20 years very little was done in this area until in the early 2000s a number of AI researchers started to formulate new inconsistency measures primarily in the context of propositional logic knowledge bases. The aim of this volume is to survey what has been done so far, to expand inconsistency measurement to other formalisms, to connect it with related topics, and to provide ideas for further research in a topic that is particularly relevant now in view of the many inconsistencies…

Comments on “Unobservable Selection and Coefficient Stability

2019

Abstract–: We establish a link between the approaches proposed by Oster (2019) and Pei, Pischke, and Schwandt (2019) which contribute to the development of inferential procedures for causal effects in the challenging and empirically relevant situation where the unknown data-generation process is not included in the set of models considered by the investigator. We use the general misspecification framework recently proposed by De Luca, Magnus, and Peracchi (2018) to analyze and understand the implications of the restrictions imposed by the two approaches.

Adherence

2016

Non-adherence to medical advice is a serious problem to patients, health policy and practitioners. This article outlines concepts of behavioral economics that might lead a patient to decide against the provider's recommendations and thus to be non-adherent. Especially the timing of pay-offs and dynamic inconsistency, their uncertainty and ambiguity aversion, loss-aversion and numerous heuristics like the peak-end-rule are discussed. The paper concludes with some hints on “libertarian” paternalism that may improve the situation.

L’idealismo trascendente tra Cusano e Leibniz

2013

I aim at demonstrating how both Nicholas of Cusa and Leibniz glean from the platonic school of thought the idealistic notion of ‘truth as expression’, orienting it towards the singularity of being. I will also reveal a second assumption derived from the philosophia perennis by both thinkers: the idea of philosophy as hypothetic and intersubjective undertaking. The theoretical results of this philosophical conceptualization are formulated in the name of the Possibility rather than in the name of Necessity. Under this shared perspective, Nicholas and Leibniz interpret the substantial forms (formae substantiales) as “unities without plurality”. It follows that the dialectic subjects can only b…

Typology and Representation of Alterations in Territorial Units: A Proposal

2018

Abstract This article proposes a typology of boundary changes in territorial units at two points in time. The different types of changes are organized in a hierarchy and represented homogeneously, independently of the number of territorial units involved and of the changes to them. Each alteration is described precisely and unambiguously, and it is codified to allow the information to be treated automatically. In addition to providing efficient storage of the information about these changes, a canonical representation facilitates the automatic detection of inconsistencies in the database. At the same time, the typology allows us to define backward and forward equivalence rules, which helps …

BALANCED VARIABLE ADDITION IN LINEAR MODELS

2018

This paper studies what happens when we move from a short regression to a long regression in a setting where both regressions are subject to misspecification. In this setup, the least-squares estimator in the long regression may have larger inconsistency than the least-squares estimator in the short regression. We provide a simple interpretation for the comparison of the inconsistencies and study under which conditions the additional regressors in the long regression represent a “balanced addition” to the short regression.

Comments on "Identifying inconsistency in network meta-analysis: Is the net heat plot a reliable method?"

2021

One of the biggest challenges for network meta‐analysis is inconsistency, which occurs when the direct and indirect evidence conflict. Inconsistency causes problems for the estimation and interpretation of treatment effects and treatment contrasts. Krahn and colleagues proposed the net heat approach as a graphical tool for identifying and locating inconsistency within a network of randomized controlled trials. For networks with a treatment loop, the net heat plot displays statistics calculated by temporarily removing each design one at a time, in turn, and assessing the contribution of each remaining design to the inconsistency. The net heat plot takes the form of a matrix which is displaye…
