Class "PcaLocantore" Spherical Principal Components
The Spherical Principal Components procedure was proposed by Locantore et al., (1999) as a functional data analysis method. The idea is to perform classical PCA on the the data, \ projected onto a unit sphere. The estimates of the eigenvectors are consistent and the procedure is extremly fast. The simulations of Maronna (2005) show that this method has very good performance.
Objects from the Class
Objects can be created by calls of the form
new("PcaLocantore", ...) but the
usual way of creating
PcaLocantore objects is a call to the function
PcaLocantore which serves as a constructor.
Object of class
"numeric"The quantile h used throughout the algorithm
"Pca", by class "PcaRobust", distance 2.
