SpatFD: Create a SpatFD object

In catalinavillamil/SpatFD: Functional Kriging, Functional Cokriging and Optimal Spatial Sampling of Functional Data

Description

Function that creates SpatFD objects; objects that hold all the information necessary for univariate or multivariate geostatistical prediction for functional data.

Usage

     SpatFD(data,coords,basis="Bsplines",nbasis=4,lambda=0,nharm=NULL,vp=NULL,name=NULL,add=NULL,...)
     SpatFD(data, coords, nharm=NULL, add=NULL,...)
     SpatFD(data, coords, vp=NULL, add=NULL,...)

Arguments

data	Is a matrix, data frame or fdata with the observed data
coords	A data frame or a matrix with two columns indicating X and Y coordinates
basis	A character specifying the basis functions, “Bsplines” or “Fourier”
nbasis	An integer variable specifying the number of basis functions. 4 by default.
lambda	A non negative real number specifying the amount of smoothing to be applied to the estimated functional parameter. 0 by default
nharm	The number of harmonics or principal components to compute.
vp	The percentage of variance to calculate the number of harmonics or principal components to compute.
name	Name of variable.
add	An object of class SpatFD to be added.
...	Arguments to be passed to the basis function creation (see create.bsplines.basis or create.fourier.basis).

Value

An object of class SpatFD, which inherits from list. Its components are:

SFD	An object of class SpatFD, where is specified the original data, the functional data and the components of the FPCA
