Total error vs. measurement uncertainty: the match continues.
Although 5 years have passed since the publication of a previous editorial in this journal that tried to reconcile the concepts [1], laboratory professionals are still playing the total error (TE) vs. uncertainty game. Two papers published in this issue of Clinical Chemistry and Laboratory Medicine further discuss the subject [2, 3], which was revitalized by the organization of the 1st EFLM Str...
متن کاملApplication of traceability concepts to analytical quality control may reconcile total error with uncertainty of measurement.
In this issue of CCLM, a contribution from Prof. James West-gard (1) rekindles the debate, started 10 years ago by Dr. Dybkaer (2, 3), who opposed total error and the uncertainty of measurements performed in clinical laboratories. In agreement with the ISO 15189 standard (4), both scientists agree in principle that laboratories should know the uncertainty of their results for assessing whether ...
متن کاملMeasurement error models with uncertainty about the error variance 1 Running head : MEASUREMENT ERROR MODELS WITH UNCERTAINTY ABOUT THE ERROR VARIANCE
It is well known that measurement error in observable variables induces bias in estimates in standard regression analysis and that structural equation models (SEM) are a typical solution to this problem. Often, multiple indicator equations are subsumed as part of the SEM model – allowing for consistent estimation of the relevant regression parameters. In many instances, however, embedding the m...
متن کاملColloquium: Quantum root-mean-square error and measurement uncertainty relations
Recent years have witnessed a controversy over Heisenberg’s famous error-disturbance relation. Here we resolve the conflict by way of an analysis of the possible conceptualizations of measurement error and disturbance in quantum mechanics. We discuss two approaches to adapting the classic notion of root-mean-square error to quantum measurements. One is based on the concept of noise operator; it...
متن کاملSurvey Participation, Nonresponse Bias, Measurement Error Bias, and Total Bias
A common hypothesis about practices to reduce survey nonresponse is that those persons brought into the respondent pool through persuasive efforts may provide data filled with measurement error. Two questions flow from this hypothesis. First, does the mean square error of a statistic increase when sample persons who are less likely to be contacted or cooperate are incorporated into the responde...
