|Title:||Weighted Means Statistics in Interlaboratory Studies|
|Published:||May 06, 2009|
|Abstract:||The usefulness of weighted means statistics as a consensus mean estimator in collaborative studies is discussed. A random effects model designed to combine information from several sourcesis employed to justify their appeal to metrologists. Some methods of estimating the uncertainties and of constructing confidence intervals are reviewed.|
