Models of Cohen measurability

open access: yesAnnals of Pure and Applied Logic, 2014
We show that in contrast with the Cohen version of Solovay's model, it is consistent for the continuum to be Cohen-measurable and for every function to be continuous on a non-meagre set.

Parametrized Measure Models [PDF]

open access: yesBernoulli, 2017
We develope a new and general notion of parametric measure models and statistical models on an arbitrary sample space $Ω$ which does not assume that all measures of the model have the same null sets. This is given by a diffferentiable map from the parameter manifold $M$ into the set of finite measures or probability measures on $Ω$, respectively, which

Model-Based Manifest and Latent Composite Scores in Structural Equation Models

open access: yesCollabra: Psychology, 2019
Composite scores are commonly used in the social sciences as dependent and independent variables in statistical models. Typically, composite scores are computed prior to statistical analyses.

Construct measurement error in latent social network relationship: An item response theory based latent space model

open access: yes, 2023
Research on measurement error in social network analysis has primarily focused on proxy measurement error, which refers to inadequate or inaccurate observations of proxy measurements of social relationships.

Robust Localization System Fusing Vision and Lidar Under Severe Occlusion

open access: yesIEEE Access, 2020
Localization is one of the most fundamental problems for mobile robot. Aiming at the phenomenon that robot is prone to be lost in navigation under severe occlusion, a robust localization system combining vision and lidar is proposed in this paper.

Ontology development for measurement process and uncertainty of results [PDF]

open access: yes, 2021
Copyright © The Author(s) 2021. In future manufacturing and metrology, there is increasing demand to organize relevant metadata and knowledge to present information in semantically meaningful, reusable, easily accessible, and interoperable form.

Transition Models with Measurement Errors [PDF]

open access: yesReview of Economics and Statistics, 1999
Les auteurs estiment un modèle de transition entre états sur le marché du travail qui tient compte des erreurs de classification dans les déclarations des états occupés. Ces erreurs de mesure viennent du caractère partiellement rétrospectif du questionnaire de l'enquête.

Consistent estimation in an implicit quadratic measurement error model

open access: yes, 2004
An adjusted least squares estimator is derived that yields a consistent estimate of the parameters of an implicit quadratic measurement error model. In addition, a consistent estimator for the measurement error noise variance is proposed.

A Generic Model for Quantum Measurements [PDF]

open access: yesEntropy, 2019
In previous articles, we presented a derivation of Born’s rule and unitary transforms in Quantum Mechanics (QM), from a simple set of axioms built upon a physical phenomenology of quantization—physically, the structure of QM results of an interplay between the quantized number of “modalities” accessible to a quantum system, and the continuum of ...
