Likelihood Ratio Methods for Monitoring Parameters of a Nested Random Effect Model
监测嵌套随机效应模型参数的似然比方法
In many practical situations the variance of a set of measurements can be attributed to several known sources of variability. For example, if several measurements of each item of a lot are taken, then one may need to deal not only with the within-item variability, but also with item-to-item within-lot and lot-to-lot components of variability. In such cases conventional control charts tend to produce an unacceptably high rate of false alarms and in general represent a rather…
