Multiple comparisons procedures.
In biomedical research, a common question posed by investigators is whether or not an outcome of interest differs significantly between multiple independent groups of subjects in the study sample. For example, in a randomized clinical trial focusing on differences in a parameter of cardiovascular health such as systolic blood pressure or heart rate that is measured on a continuum, one might mak...

Introduction: The aim of this study was to use Classical Test Theory (CTT) software for qualitative and quantitative analysis of Multiple Choice Questions (MCQ) for Master students of health discipline. Methods: This study was carried out on two groups each including 50 undergraduate students of public health, and two groups of 50 and 26 undergraduate students of occupational health. The final...
متن کاملSample size determination for step-down multiple test procedures: Orthogonal contrasts and comparisons with a control
Abstrucr; We address the problem of sample size determination for step-down multiple comparison procedures (MCP’s) for two nonhierarchical families orthogonal contrasts and comparisons with a control, in order to guarantee a specified requirement on their power. The results for the corresponding single-step MCP’s are obtained as special cases. Numerical calculations of the sample sizes to guara...
متن کاملSimultaneous test procedures in terms of p-value copulae
At least since Gabriel (1969), a broad class of multiple comparison procedures, socalled simultaneous test procedures (STPs), is established in the statistical literature. Elements of an STP are a testing family (H, T ), consisting of a set of null hypotheses and corresponding test statistics, and a common critical constant cα. The threshold cα with which each of the test statistics has to be c...
