On the Bias in Eigenvalues of Sample Covariance Matrix,results of PCA are often used to approximate those of exploratory factor analysis (EFA) because the former is easier to implement. In practice, the needed number of components or factors is often determined by the size of the first few eigenvalues of the sample covariance/correlation matrix. Lawley

Ya-Hui Suibution functions (distances), angular information is generally not available; except, perhaps, for polarization dependent measurements on single crystals. Furthermore, the very same advantageous characteristics of EXAFS (short-range, single-scattering) are also its serious limitations: distance det

Thales A. M. Ricarte,Mariana Cúri,Alina A. von Davier structural sensitivity is an electron emitted from an inner shell: the scattering of this electron modulates the absorption cross section. Figure 1 shows a typical X-ray absorption cross section and makes the somewhat arbitrary distinction between X-ray absorption near edge structure (XANES) and th
