Mathematical … WebSo, if the covariances average to 0, which would be a consequence if the variables are pairwise uncorrelated or if they are independent, then the variance of the sum is the sum of the variances. An example where this is not true: Let Var ( X 1) = 1. Let X 2 = X 1. Then Var ( X 1 + X 2) = Var ( 2 X 1) = 4. Share. Cite.

WebMay 26, 2015 · The matrix S = cov ( A) is m × m, has m distinct eigenvalues, and eigenvectors s 1, s 2 ... s m, which are orthogonal. The i -th principal component (some people call them "scores") is the vector z i = A s i. In other words, it's a linear combination of the columns of A, where the coefficients are the components of the i -th eigenvector of S.
