Confidence intervals for robust estimates of measurement uncertainty Open
Uncertainties arising at different stages of a measurement process can be estimated using analysis of variance (ANOVA) on duplicated measurements. In some cases, it is also desirable to calculate confidence intervals for these uncertaintie…
