Your question is clearly symmetric, and you should use procrustes with argument symmetric = TRUE or equivalently protest. richardson cap stylesWebb28 okt. 2014 · Like Gav said, the points must match each other one to one for Procrustes rotation. However, once you have a Procrustes rotation, you can naturally apply it to other matrices with the same number of columns. The number of columns is crucial: If you have 2-dim NMDS, your variables also must be mapped into these 2 dim. richardson cap with leather patch

Although it may seem unusual to think of distributions in terms of geometry, this makes more sense when we consider the distributions as point sets in some activation space.

WebbProcrustes analysis has many variations and forms. Of these forms, the generalized orthogonal Procrustes analysis (GPA) is the most useful in shape correspondence, because of the orthogonal nature of the rotation matrix.
