Matrix addition: The sum B + C of two matrices B and C having the same order is obtained by adding the corresponding elements in B and C. That is, B+C=[bij]+[cij]=[bij+cij] So, for example, if B=(53−127−5)and C=(32810−1−3)then B+C=(857126−8) Matri...

In addition to the above description of PCA, the following geometric conceptualization of PCA might be helpful. Consider a data set of 10 sample chromatograms, each composed of 20,000 pixels. The first conceptual step in applying PCA to this data set is to imagine each preprocessed and unfolde...
To properly define coordinate system basis vector, it is not enough to define the direction of those basis vectors (in other words the direction of the katex is not defined, katex is not defined, and katex is not defined axes in 3D space) but in addition, it is necessary to specify ...
is the point (generally non member), which minimises the sum of distances to all member points. This is the one we want. It is less susceptible to outliers than the centroid. In addition, unlike quasi median,gmis rotation independent. ...
