Functional Principal Component Analysis of multivariate hydrographic profiles
Description
This function computes a FPCA on multivariate hydrographic profiles.
It returns the basis of decomposition, also called the vertical modes.
Usage
fpca(fdobj)
Arguments
fdobj
fd objects (list) of the splines construction containing coefficients, etc... This is produced by the function bspl.
Value
pca list containing the eigen (values), eigen (vectors), eigen vectors not weighted by WM (vecnotWM), deformation induced by an axis (axe) percentage of each axis (pval).
