We focus on when inference of equivalence is made in terms of the ratio of two normal means. In the presence of unspecified variances, methods such as the likelihood-ratio test use sample estimates for those variances; Bayesian models integrate them out in the posterior distribution. These ...
method is used to test for practical equivalence between the means or the ratio of two standard deviations. for equivalence tests about means, see schuirmann (1987). two one-sidedttests are constructed for the null hypotheses that the true difference or true ratio exceeds the threshold values....

The new approach can be readily adopted for (i) commonly used equivalence limits such as difference and the ratio of treatment means and (ii) both one-sided non-inferiority and two-sided equivalence trials. We illustrate our methodology with two medical examples and demonstrate how test results ...
based on all pairwise equivalence tests on ratio of gene expressions, to select genes that are stable enough to be used as reference genes among a set a candidate genes. This statistical procedure controls the error of selecting an inappropriate gene. Application to 30 candidate reference genes ...
In statistical applications, such as a comparison of two items, it is useful to know whether one item is equivalent to another. Similarly it is often desir... DM Ennis,JM Ennis - 《Food Quality & Preference》 被引量: 48发表: 2010年 Applying Tests of Equivalence for Multiple Group Comparis...

The orbit of Mercury is well-suited to test the EP, which describes the equality between gravitational and inertial masses. The EP has been partially demonstrated by laboratory experiments, to a precision of ~1 × 10−13with recent torsion-balance tests7. However, these precise results on...
For a survival outcome, the comparative assessment can be made using survival probabilities or where appropriate, the hazard ratio. SAS POWER and FREQ procedures offer options for performing the tests of hypotheses, and assessment of statistical power and sample size for conducting equivalence and non...
