BOOTSTRAPPING ANALOGS OF THE ONE WAY MANOVA TEST
The classical one way MANOVA model is used to test whether the mean measurements are the same or differ across p groups, and assumes that the covariance matrix of each group is the same. This work suggests using the Olive (2017abc) bootstrap technique to develop analogs of one way MANOVA test. A …

Smallest Simultaneous Confidence Sets, Using Sufficiency and Invariance, With Applications to Manova and Gmanova
The thesis first describes how sufficiency and invariance considerations can be applied in problems of confidence set estimation to reduce the class of set estimators under investigation. Let X be a random variables taking values in with distribution P(,(theta)), (theta) (epsilon) (THETA), and …

Power comparisons of four post-MANOVA tests under variance-covariance heterogeneity and non-normality in the two group case
… to investigate the relative power of four post-MANOVA tests under violations of multivariate homoscedasticity and normality. The four methods for analyzing multivariate group differences following a significant Hotelling's T² were: (1) univariate F; (2) Bonferroni; (3) multiple Bonferroni; and …

New methods for fixed-margin binary matrix sampling, Fréchet covariance, and MANOVA tests for random objects in multiple metric spaces
Many approaches to the analysis of network data essentially view the data as Euclidean and apply standard multivariate techniques. In this dissertation, we refrain from this approach, exploring two alternate approaches to the analysis of networks and other structured data. The first approach seeks …

A type I error investigation of modified Scheffe-based multiple-comparison procedures in factorial ANOVA, MANOVA, and multiple-regression situations
… in factorial ANOVA designs, one-factor MANOVA comparisons, and tests of partial regression coefficients in multiple regression, in specific regard to the practical utility of modified (sequential) Scheffe-based procedures. Researchers who are concerned with maintaining familywise Type I …

Players' and coaches' perceptions of soccer coaches' specific leadership behaviours
… players and the coaches was 10:1. Results of the MANOVA revealed significant multivariate differences between players' and coaches’ perceptions of coaches' behaviours. The univariate ANOVAs revealed that Coaches' and players' perceptions differed significantly on ten of the 14 specific behaviours. …

Play as the zone of proximal development: collaborative constructive block play
… of an overall multivariate analysis of variance (MANOVA) conducted for boys and girls found a significant interaction between treatment (play level) and gender. A follow-up MANOVA for girls was also significant. Subsequent univariate tests found significant differences in block play complexity of …

Date rape attitudes intervention: A controlled outcome study
… control) x 3 (pre-test, post-test, follow-up) MANOVA (multivariate analysis of variance) was used to analyze the data. The MANOVA was significant for the effect of time, F (4, 83) = 2.27, p < .05. Both conditions reported a greater sensitivity to rape-related attitudes over time. Implications …

Beta-ensembles with covariance
… samplers for the [beta]-Wishart and [beta]-MANOVA ensembles with diagonal covariance. These generalize the [beta]-ensembles of Dumitriu-Edelman, Lippert, Killip-Nenciu, Forrester-Rains, and Edelman-Sutton, as well as the classical [beta] = 1, 2,4 ensembles of James, Li-Xue, and Constantine. …

Differences in Interpersonal Problems Among Bereaved vs. Non-Bereaved College Students: The Impact of Loneliness and Social Inhibition
… inhibition were the dependent variables. A MANOVA was conducted to explore the differences in loneliness and social inhibition among the independent variables. Based on this analysis, no significant differences were found between bereaved and non-bereaved young adults, nor where there gender …
