We present simultaneous fiducial generalized confidence intervals for the successive differences of the location parameters of several exponential distributions with unequal scale parameters, and show that they have correct coverage probability asymptotically. Our simulation results indicate...

Permutation methods using median differences for simultaneous pairwise comparisons with a control are investigated. Simulation results suggest that the permutation methods are generally more powerful than the Dunnett procedure when data are from nonnormal distributions. A new procedure is shown...

The positive and negative predictive values of a binary diagnostic test are measures of the clinical accuracy of the diagnostic test, which depend on the sensitivity and specificity of the diagnostic test and the disease prevalence, and therefore they are two interdependent parameters. The...

Asymptotic simultaneous lower (upper) confidence bounds for risk differences arising from comparing several treatments to a common control are constructed by inverting the maximum (minimum) of score statistics. With a few exceptions, these bounds perform better in terms of simultaneous coverage...

When analyzing high-throughput genomic data, the multiple comparison problem is most often addressed through estimation of the false discovery rate (FDR), using methods such as the Benjamini & Hochberg, Benjamini & Yekutieli, the q-value method, or in controlling the family-wise error rate...

We present two new tests for stochastic ordering in a standard two-sample scheme. We approach the problem via its reparametrization in terms of Fourier coefficients in some corresponding system of functions and combining the resulting empirical Fourier coefficients. The empirical Fourier...

For testing a set of null hypotheses, the chance of at least one significant result is much higher than the nominal size of each test. The P-value of Simes (1986) controls type-1 error under weak conditions and is far less conservative that the Bonferroni P-value when the tests are correlated....

This paper presents an empirical analysis of the response of several methods proposed in literature to construct indices for consistent multiple comparison. In this article we consider also the close formal connection between the comparison of preference judgements and the comparison of economic...

The purpose of this study is to better understand the negative image associated with public education as compared to catholic and independent schools in Australia. This is done by examining parents' attitudes toward the three school sectors to determine the brand image parents perceive of...
