摘要：
An analysis of variance (ANOVA) is widely used for measurement system analysis. It assumes that the measurement error is normally distributed, which may not be seen in some industrial cases. In this study, the estimate of precision-to-tolerance ratio (PTR) is obtained by using weighted standard deviation for the case where the measurement error is non-normally distributed. The point estimate for the case with normally distributed measurement error is compared to that with non-normally distributed measurement errors through computer simulation.
