Power Estimation in Multivariate Analysis of Variance [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2007
Power is often overlooked in designing multivariate studies for the simple reason that it is believed to be too complicated. In this paper, it is shown that power estimation in multivariate analysis of variance (MANOVA) can be approximated using a F ...

Multivariate analysis of curvature estimators [PDF]

open access: yesComputer-Aided Design and Applications, 2016
ABSTRACTPrincipal curvature is one of the defining features of surfaces studied in differential geometry. While well-defined and easy to evaluate for smooth surfaces, it cannot be evaluated exactly if the surface is represented by a polygon mesh, unless some special conditions apply. Nevertheless, estimating the curvature of a surface mesh is a crucial

Performance analysis of multivariate complex amplitude estimators [PDF]

open access: yesIEEE Transactions on Signal Processing, 2005
We consider multivariate complex amplitude estimation in the presence of unknown interference and noise. Two multivariate approaches [Maximum Likelihood (ML) and Capon] are provided. We derive the closed-form expression of the Crame/spl acute/r-Rao bound (CRB) for the unknown complex amplitudes.

Multivariate Meta-Analysis of Genetic Association Studies: A Simulation Study. [PDF]

open access: yesPLoS ONE, 2015
In a meta-analysis with multiple end points of interests that are correlated between or within studies, multivariate approach to meta-analysis has a potential to produce more precise estimates of effects by exploiting the correlation structure between ...

Estimation of a Matrix of Heterogeneity Parameters in Multivariate Meta-Analysis of Random-Effects Models [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2014
Multivariate meta-analysis has potential over its univariate counterpart. The most common challenge in univariate or multivariate meta-analysis is estimating heterogeneity parameters in non-negative domains under the random-effects model assumption.
