PCA with out Gaussian elimination method solution of the following system of linear equations to solve a number of Gauss elimination coefficient matrix contains a very small number of cases, it can have an enormous round-off errors, leading to algorithm failure. A simple and effective way to improve in carrying out elements of the current column to 0 of consumer computing, the choice of the current column j corresponds to the line (j to n) in a larger absolute number of firms as a principal, In this way, a lot of errors will be reduced
