Equivalence Tests for Paired Means (Simulation)
This procedure allows you to study the power and sample size of tests of equivalence of means of two correlated variables. Schuirmann’s (1987) two one-sided tests (TOST) approach is used to test equivalence. The paired t-test is commonly used in this situation. Other tests have been developed for the case when the data are not normally distributed. These additional tests include the Wilcoxon si...
متن کاملNovel tests for evaluating two ROC curves under paired samples.
Disease prevention is important and can be accomplished by developing diagnostic tests. The receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC) are used to assess the accuracy of diagnostic tests. The assessment for the superiority between evaluating two diagnostic tests is needed when comparing two diagnostic tests. Existing tests are constructed by comparing t...
متن کاملEquivalence Tests
Scientists should be able to provide support for the absence of a meaningful effect. Currently, researchers often incorrectly conclude an effect is absent based a nonsignificant result. A widely recommended approach within a frequentist framework is to test for equivalence. In equivalence tests, such as the two one-sided tests (TOST) procedure discussed in this article, an upper and lower equiv...
متن کاملPaired Preference Tests
In consumer research, the role of the paired preference test appears to be sacrosanct, whether deserved or not. Paired preference simply means putting one product up against another, and instructing the respondent to indicate which one the respondent prefers. The ‘preference’ measure does not show how much one product is liked (or how much more one product is liked versus another). Rather, the ...
متن کاملTests for Paired Means
The one-sample paired t-test may be used to test whether the mean difference of two populations is greater than, less than, or not equal to a specific value. Because the t distribution is used to calculate critical values for the test, this test is often called the paired t-test. If the standard deviation of the differences is known, the normal distribution is used instead of the t distribution...
