The principle of correlation
Did you know?
WebbCanonical correlation is a term for an analysis of correlation among items in two lists (vectors of variables). ... Recently, research has also involved using the concept of sparseness for other statistical methods, e.g., principal component analysis in Witten et al. (2009) and partial least squares in Lê Cao et al. (2009a, 2009b). WebbPrincipal component analysis (PCA) is one popular approach analyzing variance when you are dealing with multivariate data. You have random variables X1, X2,...Xn which are all correlated (positively or negatively) to varying degrees, and you want to get a better understanding of what's going on. PCA can help.
WebbThe basic principle and the algorithm of a digital image correlation method, and the procedure for obtaining displacements and strains are described. In order to describe the basic principle precisely, only in-plane displacement and strain measurement of a planar object are explained. WebbPrinciples of Correlation Analysis.

WebbThe first is the principle of correlation itself, which claims essentially that we can only know the correlate of Thought and Being; what lies outside that correlate is unknowable. The second is termed by Meillassoux the principle of factiality, which states that things could be otherwise than what they are. WebbSo the eigenvalues of the covariance matrix are the squares of the standard deviations (i.e, variances) of the principal components and the principal components themselves are same as eigenvectors of covariance matrix (though signs may be opposite as they are here). Thanks for providing the details.
