A Truly Multivariate Approach to Manova
All too often researchers perform a Multivariate Analysis of Variance (MANOVA) on their data and then fail to fully recognize the true multivariate nature of their effects. The most common error is to follow the MANOVA with univariate analyses of the dependent variables. One reason for the occurrence of such errors is the lack of clear pedagogical materials for identifying and testing the multi...
متن کاملHigh-dimensional sparse MANOVA
This paper considers testing the equality of multiple high-dimensional mean vectors under dependency. We propose a test that is based on a linear transformation of the data by the precision matrix which incorporates the dependence structure of the variables. The limiting null distribution of the test statistic is derived and is shown to be the extreme value distribution of type I. The convergen...
متن کاملComparing Two Sports Injury Surveillance Systems: A Novel Systematic Approach
Purpose: The present study aimed to compare two sports injury surveillance systems per the sports injury recording system of the sports medicine federation. Methods: A sports injury surveillance system was implemented to collect injury data. Athletic trainers recorded athletes’ sports injuries in soccer, volleyball, handball, taekwondo, and wrestling for 6 months in their user account via a sm...
متن کاملLocal Eigenvalue Density for General MANOVA Matrices
We consider random n× n matrices of the form (XX∗ + Y Y ∗)− 1 2 Y Y ∗ (XX∗ + Y Y ∗)− 1 2 , where X and Y have independent entries with zero mean and variance one. These matrices are the natural generalization of the Gaussian case, which are known as MANOVA matrices and which have joint eigenvalue density given by the third classical ensemble, the Jacobi ensemble. We show that, away from the spe...
متن کاملThe Beta-MANOVA Ensemble with General Covariance
We find the joint generalized singular value distribution and largest generalized singular value distributions of the β-MANOVA ensemble with positive diagonal covariance, which is general. This has been done for the continuous β > 0 case for identity covariance (in eigenvalue form), and by setting the covariance to I in our model we get another version. For the diagonal covariance case, it has ...
