Nonparametric Predictive Inference for Multiple Comparisons
… Predictive Inference (NPI) for several multiple comparisons problems. We introduce NPI for comparison of multiple groups of data including right-censored observations. Different right-censoring schemes discussed are early termination of an experiment, progressive censoring and competing …

The extension of the multiple comparisons test to lattice designs
In many investigations, an experimenter is interested in comparing the effects of a number of experimental treatments, such as yields of several new agriculture varieties, results of several different production procedures, or effects of various raw materials on a final product. In this type of …

Composite Likelihood: Multiple Comparisons and Non-Standard Conditions in Hypothesis Testing
… reducing the dimension. We study the problem of multiple hypothesis testing for multidimensional clustered data. The problem of multiple comparisons is common in many applications. We propose to construct multiple comparisons procedures based on composite likelihood statistics. The simultaneous …

Asymptotic Expansions for Studentized M-Estimators With Applications to Multiple Comparisons
Consider the one-way layout with Y(,ij) being the i-th observation from group j, j = 1(1)p, i = 1(1)n(,j). Let N denote the total number of observations. Assume Y(,ij) = (theta)(,j) + e(,ij), where the e's are independent random disturbances with a common symmetric, but not necessarily normal,(, ) …

Applications of stochastic simulation in two-stage multiple comparisons with the best problem and time average variance constant estimation
… We develop two-stage selection and multiple-comparison procedures for simulations under a general framework. The assumptions are that each alternative has a parameter estimation process that satisfies a random- time-change central limit theorem (CLT), and there is a weakly consistent …

Systematic classification of black bears in the southeastern United States
… (p<0.001, Kruskal-Wallis test, α=0.05 for multiple comparisons). Louisiana and Florida black bear populations share the same degree of genetic similarity within and between populations, and are more closely related to each other than they are to American black bear populations (p<0.001, …

Fine Motor Skills, Processing Speed, And White Matter Integrity Among Pediatric Brain Tumor Survivors Who Received Proton Radiotherapy
… motor/processing speed outcomes was tested with multiple regression models. Analyses revealed that the CSI group had significantly worse fine motor speed/dexterity and psychomotor processing speed than the focal group. DTI analyses of white matter integrity showed mixed results, with weaker …

White matter correlates of neuropsychological function in young adult methamphetamine users
… however, these did not survive corrections for multiple comparisons. Conclusion: Cognitive performance and white matter integrity did not differ between young MA dependent subjects and healthy controls. Whatever differences that were found in white matter did not survive correction for multiple …

Genetic Risk Factors for PTSD: A Gene-Set Analysis of Neurotransmitter Receptors
… 151,447 controls). Prior to controlling for multiple comparisons, 7 of the investigated gene-sets reached statistical significance at the p ≤ .05 level. However, after controlling for multiple comparisons, none of the investigated gene-sets reached statistical significance. Due to limited …

Test anxiety and age: as we grow older do we become more test anxious?
… score for the sixth grade was the lowest. A multiple comparisons analysis revealed a significant difference in test anxiety levels between the second and sixth grade. However, the difference was not an increase in test anxiety, but a decrease in test anxiety. The reasons for the decrease in …

A spatial stochastic programming model for timber and core area management under risk of stand-replacing fire
… on a sample set of random fire. We integrate multiple model runs to evaluate the persistence of period-one solutions under the influence of stochastic fires. Follow-up simulations were used to support multiple comparisons of different candidate forest management alternatives for the first time …

Immunohistochemical analysis of a panel of human and murine markers on xenografted human vaginal mucosa: a comparative study
… ANOVA with subsequent Friedman’s test for multiple comparisons. Since the sample size was small, the power of the test statistic was enhanced by including Dunn’s post-test for further multiple comparisons. A strong positive expression of all cytokeratins was detected in both normal and …

The Effect of Hippotherapy on Ten Children with Cerebral Palsy
… total GMFM score. Tukey's procedure for post hoc multiple comparisons determined the significant effect of hippotherapy.

A power study of multiple range and multiple F tests
In the study of multiple comparisons tests the following topics were discussed: (i) extension to the general case of certain properties and results which previously had been given for three and four means only, (ii) power vectors and average power, (iii) expressions of power for the multiple range …

Functional Near-Infrared Spectroscopy (fNIRS) Based Functional Connectivity Alterations Associated with Delirium in Critically Ill Children: An Exploratory Study
… with delirium severity after correction for multiple comparisons. These findings suggest that fNIRS-derived FC may offer an objective, brain-based biomarker of delirium presence in pediatric critical care, with potential to complement existing behavioural assessment tools.
