Measurement Error and Statistical Disclosure Control
Statistical agencies release microdata to researchers after applying statistical disclosure control (SDC) methods. Noise addition is a perturbative SDC method which is carried out by adding independent random noise to a continuous variable or by misclassifying values of a categorical variable according to a probability mechanism. Because these errors are purposely introduced into the data by th...
متن کاملStatistical methods for assessing measurement error (reliability) in variables relevant to sports medicine.
Minimal measurement error (reliability) during the collection of interval- and ratio-type data is critically important to sports medicine research. The main components of measurement error are systematic bias (e.g. general learning or fatigue effects on the tests) and random error due to biological or mechanical variation. Both error components should be meaningfully quantified for the sports p...
متن کاملAssessing Nonresponse Bias and Measurement Error Using Statistical Matching
The estimation of nonresponse bias and measurement error share the problem of usually not having a criterion to assess the quality of the estimate. Nonresponse bias analysis often uses responders within the survey sample who are in some way similar to nonresponders to estimate the potential bias. This depends on the variables within the survey being related to both the likelihood of responding ...

15 صفحه اولMultivariate Statistical Methods for Total Quality Measurement
In this paper, a brief outline of the evolution of the statistical techniques for the measurement of quality is firstly sketched. At the same time, the need for multivariate procedures is justified from both methodological and application points of view and a proposal of non parametric control charts is shown. The attention is then focused on visualising and monitoring quality. The peculiar fea...
