Background: Principal component analysis (PCA) is a method that identifies common directions within multivariate data and presents the data in as few dimensions as possible.One of the advantages of PCA is its objectivity, as the same results can be obtained regardless of who performs the analysis.However, PCA is not a robust method and is sensitive to noise.Consequently, Games the directions identified by PCA may deviate slightly.If we can teach PCA to account for this deviation and correct it, the results should become more comprehensible.
Methods: The top two PCA results were rotated using a rotation unitary matrix.Results: These contributions were determined and compared with the original.At smaller rotations, the change in contribution was MLB Boxes also small and the effect on independence was not severe.The rotation made the data considerably more comprehensible.Conclusions: The methods for achieving this and an issue with this are presented.
However, care should be taken not to detract from the superior objectivity of PCA.
