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