Compute the shape changes along the common axis of deformations
Compute the shape changes between two blocks of 2D or 3D shape coordiantes along the common axis of deformations defined by each dimension of the latent space
plsCoVarCommonShape(pls, i, sdcommon = 1)
pls |
object of class "pls2B" |
i |
integer: dimension of latent space to show shape changes for |
sdcommon |
standard deviations derived from scores scaled to a consensus scale |
returns an k x m x 2 array with the common shape changes associated with +-sdcommon SD of the i-th latent dimension
this give the same results as plsCoVar, however, using common shape vectors as suggested by Mitteroecker and Bookstein (2007)
