Although stated frequently, the above statement is simply false. At
best it reflects a basic misunderstanding of the use of principal
components analysis for the analysis of grids.
Recently W. Chambers posted a 'mandala grid'. If you are not among the
happy few people, who can see the basic structure underlying this grid
without an technical tools, do a PCA and you may be surprised what PCA
can do for your understanding of relations among elements and constructs
and between elements and constructs.
