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
.
1  biplotEsaPseudo3d(x, center = 4, g = 1, h = 1, ...)

x 

center 
Numeric. The type of centering to be performed.
0= no centering, 1= row mean centering (construct),
2= column mean centering (elements), 3= doublecentering
(construct and element means),
4= midpoint centering of rows (constructs).
Eigenstructure analyis uses midpoint centering ( 
g 
Power of the singular value matrix assigned to the left singular
vectors, i.e. the constructs. Eigenstructure analyis uses

h 
Power of the singular value matrix assigned to the right singular
vectors, i.e. the elements. Eigenstructure analyis uses
