Equivalence Tests for Paired Means (Simulation)

ثبت نشده
چکیده

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 signed-ranks test, the sign test, and the computer-intensive bootstrap test.

Equivalence test and confidence interval for the difference in proportions for the paired-sample design.

This paper considers a model for the difference of two proportions in a paired or matched design of clinical trials, case-control studies and also sensitivity comparison studies of two laboratory tests. This model includes a parameter indicating both interpatient variability of response probabilities and their correlation. Under the proposed model, we derive a one-sided test for equivalence bas...

On Thurstone's Model for Paired Comparisons and Ranking Data

We investigate by means of a simulation study whether standard structural equation modeling techniques are suitable for estimating an unrestricted Thurstonian model to: (a) multiple judgment paired comparisons data, and (b) ranking data. We point out that Thurstone's (1927) original model is not a proper model for multiple judgment paired comparisons data as it assigns zero probability to all i...

Impact of Sample Size and Variability on the Power and Type I Error Rates of Equivalence Tests: A Simulation Study - Practical Assessment, Research & Evaluation

The question of equivalence between two or more groups is frequently of interest to many applied researchers. Equivalence testing is a statistical method designed to provide evidence that groups are comparable by demonstrating that the mean differences found between groups are small enough that they are considered practically unimportant. Few recommendations exist regarding the appropriate use ...

Testing for Multivariate Equivalence with Random Quadratic Forms

Multivariate equivalence testing becomes necessary whenever the similarity rather than a difference between several treatment groups with multiple endpoints has to be shown. This problem occurs in various applications, including bioequivalence or the comparison of dissolution profiles. Therefore, several tests have been suggested during the last decade for the assessment of multivariate equival...

Some Equivalence Classes in Paired Comparisons

Introduction. In a paired comparison experiment n judges give a preference in some or all of the (~) pairs of t items. Frequently the purpose of the experiment is to test the null hypothesis that every preference is equally likely against a vaguely defined alternative of consistency. Our purpose is to study several of the tests used, from the point of view of a natural equivalence relation whic...
