TESTING EQUALITY OF TWO MEAN VECTORS AND SIMULTANEOUS CONFIDENCE INTERVALS IN REPEATED MEASURES WITH MISSING DATA
In this paper, we derive the exact distribution of a new test statistic for the equality of two mean vectors in the intraclass correlation model when monotone missing observations occur. Simultaneous confidence intervals for all contrasts of two mean vectors are given by using the idea in Seo and Srivastava (2000). Finally, in order to evaluate the procedure proposed in this paper, we investigate the power function of a new test statistic and the widths of simultaneous confidence intervals. The numerical results of a real example and simulation study are presented.
