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...

Although many commonly-used inference techniques for matched pairs are members of this class, some of the more appealing inference...
Share on Facebook matched pairs [′macht ′perz] (statistics) The design of an experiment for paired comparison in which the assignment of subjects to treatment or control is not completely at random, but the randomization is restricted to occur separately within each pair. ...
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...

testIntervalestimationmatchedpairThere are many epidemiologic studies or clinical trials, in which we may wish to establish an equivalence rather than to detect a difference between the distributions of responses. In this paper, we develop test procedures to detect equivalence with respect to the ...

Given the lack of reliable evidence on the utility of continuous lateral rotational therapy (CLRT) in chest trauma, we performed a single-centre retrospective matched-pair analysis of patients treated either with CLRT or non-continuous manual turning after blunt thoracic trauma. Methods We included...
