Sigma metric, английский
A numeric value that characterize method performance in terms of the number of standard deviations or sigmas that fit within the tolerance limit or quality requirement of a test. for analytic processes, calculated as sigma = [(%tea – %bias)/%cv], where tea is the allowable total error or clia pt criterion for acceptable performance, %bias represents the observed inaccuracy or systematic error of the method, and %cv represents the observed imprecision or random error of the method.
