Transition Models with Measurement Errors [PDF]

Review 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.

Drifted Uncertainty Evaluation of a Compact Machine Tool Spindle Error Measurement System

Machines
The accurate measurement of spindle errors, especially quasi-static errors, is one of the key issues for the analysis and compensation of machine tool thermal errors in machining accuracy. To quantitatively analyze the influence of the measurement system’

Angle error control model of laser profilometer contact measurement

Open Physics, 2022
In controlling the angle error of laser profilometer contact measurement, the control model used in the past is subject to more external interference, which affects the measurement of other parameters, resulting in poor error control effect.

Potential impact of systematic and random errors in blood pressure measurement on the prevalence of high office blood pressure in the United States

The Journal of Clinical Hypertension, 2022
The authors examined the proportion of US adults that would have their high blood pressure (BP) status changed if systolic BP (SBP) and diastolic BP (DBP) were measured with systematic bias and/or random error versus following a standardized protocol ...

Geometric View of Measurement Errors [PDF]

Communications in Statistics - Simulation and Computation, 2011
The slope of the best fit line from minimizing the sum of the squared oblique errors is the root of a polynomial of degree four. This geometric view of measurement errors is used to give insight into the performance of various slope estimators for the measurement error model including an adjusted fourth moment estimator introduced by Gillard and Iles ...

Sustained Therapeutic Efficacy of Intravenous Plasminogen Concentrate in Pediatric Patients With Type 1 Plasminogen Deficiency: An Analysis of Dosing Parameters and Clinical Outcomes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Type 1 plasminogen deficiency (PLGD‐1) is an ultra‐rare autosomal recessive disorder caused by variants in the PLG gene and affects approximately 1.6 individuals per million. The condition is characterized by decreased plasminogen levels and impaired function, resulting in fibrin‐rich lesions on mucous membranes throughout the body.
