Which of the following are true about principal components analysis (PCA)? Assume that no two eigenvectorsof the sample covariance matrix have the same eigenvalue. A: Appending a 1 to the end of every sample point doesn’t change the results of performing PCA (except thatthe useful principal component vectors have an extra 0 at the end, and there’s one extra useless component witheigenvalue zero). B: If you use PCA to project d-dimensional points down to j principal coordinates, and then you run PCA againto project those j-dimensional coordinates down to k principal coordinates, with d > j > k, you always get the sameresult as if you had just used PCA to project the d-dimensional points directly down to k principle coordinates. C: If you perform an arbitrary rigid rotation of the sample points as a group in feature space before performingPCA, the principal component directions do not change.

Consider that you have performed Principal Component Analysis of a centered and unscaled data set, that is, the variance-covariance matrix to be analysed is not equal to the correlation matrix. To do the PCA for the same set, but now centered and scaled, Select one: a. reuse the eigenvalues, with the only change is to rescale them to add to the number of components. The eigenvectors are the same. O b. it is not possible to reuse eigenvalues nor eigenvectors. in some selected instances we can reuse eigenvalues and eigenvectors of the analysis of centered and unscaled data. C.
