Multiple-Comparison Testing

2017
So far, we have seen a couple of statistical tests which can indicate if a factor has an impact on the response or not, and which would make us reject or accept H0(μ1 = μ2 = μ3 = … = μ C ); however, they do not show how the means differ, if, indeed, they do differ.

Adaptive Sequential Testing for Multiple Comparisons

Journal of Biopharmaceutical Statistics, 2014
We propose a Markov process theory-based adaptive sequential testing procedure for multiple comparisons. The procedure can be used for confirmative trials involving multi-comparisons, including dose selection or population enrichment. Dose or subpopulation selection and sample size modification can be made at any interim analysis.

Multiple Comparisons by Rerandomization Tests

Journal of the American Statistical Association, 1983
Abstract Classical methods of simultaneous inference cannot be used with rerandomization tests without risking excessive type I errors. This is illustrated by examples that show some published methods to be invalid for multiple comparisons. However, the use of stepwise procedures is shown to remain valid with rerandomization tests.

Multiple Comparisons/Testing Issues

2009
The statistical testing of multiple genetic markers in genetic linkage and association studies is discussed and shown to lead to a multiple-testing problem. Various solutions are discussed and demonstrated on published data. The false discovery rate (FDR) and several approaches of estimating it, are mentioned.

Comparison of Two Multiple-Choice Rorschach Tests

Perceptual and Motor Skills, 1965
Seventy-three Ss were administered the SORT and HMCR in counterbalanced order. Analysis of protocols indicated that the tests bore little relationship to each other. The results seemed to indicate that the use of suggested responses might invalidate the traditional Rorschach blot-stimulus relationship.

COMPARISON OF MULTIPLE PUNCTURE LIQUID TUBERCULIN TEST WITH MANTOUX TEST

The Lancet, 1981
Two studies were performed to compare the disposable liquid tuberculin PPD 'Imotest' with the Mantoux test. While there was a tester effect in the first study indicating the need for accurate application of the imotest, the results of the second study showed that the two tests were comparable in selecting truly positive and negative tuberculin reactors.

Some Nonparametric Multiple-Comparison Tests

Perceptual and Motor Skills, 1974
Some nonparametric multiple-comparison tests are described for making both pairwise comparisons and a limited number of comparisons with k independent and k matched groups when the data consist of “bad” numbers and ranks or frequencies.

Some Rank Sum Multiple Comparisons Tests

Biometrics, 1961
A number of nonparametric tests based on ranks have been proposed for the comparison of treatments in a completely random design. For example, we have the Wilcoxon-Mann-Whitney test [21, 10], basically a two-sample test with a per-comparison error rate.
