The principle of correlation
WebbPrincipal component analysis (PCA) is one popular approach analyzing variance when you are dealing with multivariate data. You have random variables X1, X2,...Xn which are all correlated (positively or negatively) to varying degrees, and you want to get a better understanding of what's going on. PCA can help. WebbThe first is the principle of correlation itself, which claims essentially that we can only know the correlate of Thought and Being; what lies outside that correlate is unknowable. The second is termed by Meillassoux the principle of factiality, which states that things could be otherwise than what they are.
