Principal component analysis is simply a variable reduction procedure that (typically) results in a relatively small number of components that account for most of the variance in a set of observed variables [3]. In summary, both factor analysis and principal component analysis have important roles to play in social science

Principal Component Analysis Projects data onto orthogonal vectors that maximize variance. Remember, given an n nmatrix A, a nonzero vector ~x, and a scaler , if A~x= ~xthen ~xand are an eigenvector and eigenvalue of A. In PCA, the eigenvectors are uncorrelated and represent principal components. 1.Start with the covariance matrix of ...
