However, in a matched-pair design, the currently available rank-based statistics lose significant power compared to normal linear mixed model (LMM) test statistics when the LMM is true. In this article, we investigate and develop an optimal test statistic over all statistics in the form of the...
A matched pairs design is an experimental design where researchers match pairs of participants by relevant characteristics. Then the researchers randomly assign one person from each pair to the treatment group and the other to the control group. This type of experiment is also known as a matching ...
When using a hypothesis test for matched or paired samples, the following characteristics should be present:Simple random sampling is used. Sample sizes are often small. Two measurements (samples) are drawn from the same pair of individuals or objects. Differences are calculated from the matched ...

We consider the problem of testing bivariate symmetry in matched pair experiments where ( X 1, X 2) are time measurements such as failure or survival times... DM Dabrowska - 《Journal of Multivariate Analysis》 被引量: 40发表: 1989年 Signed rank statistics for coherent predictions. matched p...
When matched-pair design is used, study participants are matched together based on whichever key variable or variables are relevant to the study topic. Within a statistical study, a variable is a characteristic of the participant within the trial. For example, if the study involves people, char...
A class of statistics is proposed for the problem of testing for location difference using randomly right censored matched pair data. Each member of the class provides a conditionally distribution-free test of H0: no location difference. Simulation results indicate that powers tests basd on certain...
