Performance analysis of multivariate complex amplitude estimators [PDF]
IEEE 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.

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

A Method of Moments Estimator for Random Effect Multivariate Meta‐Analysis [PDF]
Biometrics, 2012 SummaryMeta‐analysis is a powerful approach to combine evidence from multiple studies to make inference about one or more parameters of interest, such as regression coefficients. The validity of the fixed effect model meta‐analysis depends on the underlying assumption that all studies in the meta‐analysis share the same effect size.

Mathematics, 2022 The estimation of the covariance matrix is an important topic in the field of multivariate statistical analysis. In this paper, we propose a new estimator, which is a convex combination of the linear shrinkage estimation and the rotation-invariant ...
