11. These samples may then be compared by principal component analysis . 12. SOM may be considered a nonlinear generalization of Principal components analysis ( PCA ). 13. Principal Component Analysis and general factor of intelligence in humans ( 40-50 % ). 14. Principal component analysis indicated that this shortened questionnaire was able to measure empathy reliably. 15. The Tucker decomposition is used in multilinear principal component analysis . 16. Classical examples include principal components analysis and cluster analysis. 17. Principal component analysis is used to study criteria for determining the number of factors ). 18. These include exploratory factor analysis, principal components analysis ( PCA ), and confirmatory factor analysis. 19. It has applications to the statistics of principal components analysis and the singular value decomposition. 20. The simplest approach, however, is to perform a standard principal component analysis ( PCA ).
