| Outline of Final Research Achievements |
We considered statistical hypothesis testing methods for detecting possible differences of two means when the population distributions of two samples are unknown and each sample is observed as longitudinal data. Our research showed that block resampling methods are applicable to the problem for comparison of two means, and that the testing methods based on block resampling methods are superior to traditional methods in terms of power even when sample sizes are relatively small.
