When processing actual problem often can involve many related variables, in order to analyzes the question clearly, carries on the principal components analysis to many variables, like this may be according to what is believed several has in the loss minority rest foundation many target transformati

In dealing with the actual issues tend to involve multiple variables, in order to analyze the problem more clearly, principal component analysis for multiple variables, so that data can be less loss on the basis of information into several more indicators on behalf of comprehensive indicators of sig
