lssvm-class: Class "lssvm"

Description

The Gaussian Processes object

Objects from the Class

Objects can be created by calls of the form new("lssvm", ...). or by calling the lssvm function

param:

Object of class "list" contains the regularization parameter used.

kcall:

Object of class "call" contains the used function call

type:

Object of class "character" contains type of problem

coef:

Object of class "ANY" contains the model parameter

terms:

Object of class "ANY" contains the terms representation of the symbolic model used (when using a formula)

xmatrix:
