WebHypothesis Testing The terminology we use when conducting a hypothesis test is that we either: I Have enough evidence (based on our statistic, T(X 1;:::;X n)) to reject the null hypothesis H 0 in favor of the alternative hypothesis H 1, or I We do not have enough evidence to reject the null hypothesis H 0, and so our data is consistent with the ... WebFeb 7, 2015 · Therefore, I want to perform permutation test and bootstrap. PERMUTATION TEST. Null hypothesis (H0) states that group's means are the same. This assumption in permutation test is justify by pooling groups into one sample. This ensures that the samples for two groups were drawn from the identical distribution. bus hound使用指南
