Pairwise two-sided p-values
Webequiv.test is modelled after (and borrows code from) R's t.test () and is intended to work as similarly as possible. This functions implements uniformly most powerful invariant equivalence tests for one-sample and (paired or unpaired) two-sample problems. Also supported are one-sided versions (so-called non-inferiority or non-superiority tests). Webp.value: the two-sided p-value associated with the observed statistic method : the name of the inferential statistical test estimate : estimated value of the effect size

WebThe odds of the data for Site 3 are 12:102, whence. 0.2123 / ( 1 − 0.2123) × 12 / 102 = 0.0317. This corresponds to a new probability or "p-value" of 0.0307 --remarkably close to the two-sided p-value of 0.0287 obtained for the full table. Whether we believe this intuition or not, the discrepancy in p-values is telling us that the apparently ...
