Averaging Measurements with Hidden Correlations and Asymmetric Errors
arXiv:hep-ex/0006004
Abstract
Properties of weighted averages are studied for the general case that the individual measurements are subject to hidden correlations and have asymmetric statistical as well as systematic errors. Explicit expressions are derived for an unbiased average with a well defined error estimate.
