Linear combination analysis

NettetAnalysis, or PCA. PCA produces linear combinations of the original variables to generate the axes, also known as principal components, or PCs. Computation Given a data matrix with p variables and n samples, the data are first centered on the means of each variable. This will insure that the cloud of data is centered on the origin of our princi- NettetMilan Meloun, Jiří Militký, in Statistical Data Analysis, 2011. 7.2.3 Multiple Correlation Coefficient. The multiple correlation coefficient, denoted as R 1(2,…,m), is a measure of the overall linear stochastic association of one random variable ξ 1 with the best linear combination of the other components ξ 2,…,ξ m, of the random vector ξ.The sample …
