摘要：
Certifying standard reference materials (SRM) often includes determination of a 95% confidence interval for the unknown common mean based on measurements obtained in several laboratories or by several methods. The applicable procedures have been studied extensively both in statistical and metrological literature, but none of them has been generally accepted for use. We point out a simple interval for the common mean in heteroscedastic one-way random effects model that seems to have the probability of coverage at least 0.95 overall, and discuss its properties in comparison with other available procedures.
