| Abstract: | This paper studies the detection of multiple-outliers in balanced random-effects model of one-way classification.The authors derive the likelihood ratio test under the mean- shift model in random-effects.The distribution of test statistic is given and employed to obtain the test procedure.The authors also study the test of mean-shift outlier model in error variables, and a score test is used to identify the multiple-outliers in the data. |
