Rotation of Functional Principal Components with VARIMAX Criterion
DESCRIPTION:
Principal components are often easier to interpret if they are
rotated. Among the many possible ways in which this rotation can be
defined, the VARIMAX criterion seems to give satisfactory results most
of the time.
USAGE:
varmx.pca.fd(pcafd, nharm=scoresd[2], nx=101)
REQUIRED ARGUMENTS:
pcafd
an object of class
pca.fd that is produced by function
pca.fd.
OPTIONAL ARGUMENTS:
nharm
the number of harmonics or principal components to be
rotated.
nx
the number of argument values in a fine mesh
used to define the harmonics to be
rotated.
VALUE:
a rotated principal components analysis object of class
pca.fd.
