component of variance
1Principal component analysis — PCA of a multivariate Gaussian distribution centered at (1,3) with a standard deviation of 3 in roughly the (0.878, 0.478) direction and of 1 in the orthogonal direction. The vectors shown are the eigenvectors of the covariance matrix scaled by… …
2Principal Component Analysis — Hauptkomponentenanalyse als Faktorenanalyse: Zwei Hauptkomponenten einer zweidimensionalen Punktwolke (orthogonal rotiert) Die Hauptkomponentenanalyse (englisch: Principal Component Analysis, PCA) ist ein Verfahren der multivariaten Statistik.… …
3Law of total variance — In probability theory, the law of total variance or variance decomposition formula states that if X and Y are random variables on the same probability space, and the variance of X is finite, then:operatorname{var}(X)=operatorname{E}(operatorname{v… …
4Analysis of variance — In statistics, analysis of variance (ANOVA) is a collection of statistical models, and their associated procedures, in which the observed variance in a particular variable is partitioned into components attributable to different sources of… …
5ANOVA-simultaneous component analysis — ASCA, ANOVA SCA, or analysis of variance – simultaneous component analysis is a method that partitions variation and enables interpretation of these partitions by SCA, a method that is similar to PCA. This method is a multi or even megavariate… …
6Principal component regression — In statistics, principal component regression (PCR) is a regression analysis that uses principal component analysis when estimating regression coefficients.In PCR instead of regressing the independent variables (the regressors) on the dependent… …
7Multilinear principal-component analysis — (MPCA) [1] is a mathematical procedure that uses multiple orthogonal transformations to convert a set of multidimensional objects into another set of multidimensional objects of lower dimensions. There is one orthogonal transformation for each… …
8analysis of variance — Statistics. a procedure for resolving the total variance of a set of variates into component variances that are associated with defined factors affecting the variates. Also called variance analysis. [1935 40] * * * …
9analysis of variance — noun a statistical method for making simultaneous comparisons between two or more means; a statistical method that yields values that can be tested to determine whether a significant relation exists between variables • Syn: ↑ANOVA • Topics:… …
