摘要: Several recently published studies (Nichols 1977, Feoli Noy-Meir & Whittaker 1977) have made a fundamental contribution to clarify certain misunderstandings that been linked the application of PCA and interpretation its results. It can be concluded with options such as data transformation, standardization variables, different similarity measures, axis rotation, is ecologically appropriate. Nichols (1977) discussed three important aspects
