A new chart based on sample variances for monitoring the covariance matrix of multivariate processes
(Springer London Ltd, 2009-04-01)
In this article, we propose a control chart for detecting shifts in the covariance matrix of a multivariate process. The monitoring statistic is based on the standardized sample variance of p quality characteristics we ...

Estimation of segregation variance for birth weight in beef cattle
(Elsevier, 2002-08)
Genetic evaluation using multibreed covariance theory requires estimating the segregation variance. The segregation variance is the amount by which the additive variance in the F2 exceeds that in F1. The goal of this ...
Using industry momentum to improve portfolio performance
(Elsevier Science Bv, 2012-05)
Minimum-variance portfolios, which ignore the mean and focus on the (co)variances of asset returns, outperform mean-variance approaches in out-of-sample tests. Despite these promising results, minimum-variance policies ...
