The variance-covariancematrix based on the price regressions is of particular interest. By constructing the exercise as a vector autoregression, forecasts of the variance-covariancematrix for prices could also be obtained. First-order autoregressive covariance was chosen for the structure of the variance-covariancematrix. The mean, standard deviation, variance-covariancematrix, and correlation matrix are calculated from the measurement vectors.

Empirical orthogonal function analysis proceeds instead from the variance-covariancematrix which again is biased to the eastern longitudes.

From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Hypotheses of invariance across groups of the covariance structure, structural matrix, variance-covariance matrices of exogenous variables, endogenous variables and residuals were sequentially tested. However, the variance-covariance matrices were not different for girls and boys. Often the principal components with higher variances (the ones based on eigenvectors corresponding to the higher eigenvalues of the sample variance-covariancematrix of the explanatory variables) are selected as regressors.

In order to explore further the genetic architecture of schizotypal traits, independent and common pathway models were fitted to the variance-covariance matrices. It should be noted that, although the models were fit to variance-covariance matrices, standardized estimates are being reported. Entire genetic variance-covariance matrices, as well as their individual components, were compared between populations by means of likelihood ratio tests. Then they use the estimated variance-covariance matrices to calculate the cross-market correlation coefficients (and their asymptotic distributions) for each set of markets and periods.
