Stata 9 displays principal components in unit normalisation, but one can diplay the principal components in eigenvalue normalisation by typing: estat loadings, cnorm(eigen)
But how can I get a rotated version of these principal components in eigenvalue normalisation?
It seems that stata uses the principal components in unit normalisation for rotating even after diplaying the principal components in eigenvalue normalisation:
pca v132 v1550 v148 v149 v150 v1330, mineigen(1)
estat loadings, cnorm(eigen)
rotate
And it also seems that stata dispays the unrotated principal components in eigenvalue normalisation after the roation:
pca v132 v1550 v148 v149 v150 v1330, mineigen(1)
rotate
estat loadings, cnorm(eigen)
