Principal component analysis of the data. Centralise and normalize (standardise) data, Calculate principal components and the corresponding loads(eigenvalues of the correlation matrix). Present the eigenvalues as aplot (eigenvalue as function of its number). How many major components should be retained according to theKaiser rule (for major components the eigenvalues λ>1)? According tothe conditional number rule (for all major components λmax/λ
