The ESA is
a special type of biplot suggested by Raeithel (e.g. 1998).
It uses midpoint centering as a default. Note that the eigenstructure analysis
is just a special case of a biplot that can also be produced using the
biplot2d function with the arguments
center=4, g=1, h=1.
Here, only the arguments that are modified for the ESA biplot are described.
To see all the parameters that can be changed see biplot2d
and biplotPseudo3d.
biplotEsaPseudo3d(x, center = 4, g = 1, h = 1, ...)repgrid object.
Numeric. The type of centering to be performed.
0= no centering, 1= row mean centering (construct),
2= column mean centering (elements), 3= double-centering
(construct and element means),
4= midpoint centering of rows (constructs).
Eigenstructure analysis uses midpoint centering (4).
Power of the singular value matrix assigned to the left singular
vectors, i.e. the constructs. Eigenstructure analysis uses
g=1.
Power of the singular value matrix assigned to the right singular
vectors, i.e. the elements. Eigenstructure analysis uses
h=1.
Additional parameters for be passed to biplotPseudo3d.
