## 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

### Slots

`kernelf`:

  Object of class `"kfunction"` contains the kernel function used

`kpar`:

  Object of class `"list"` contains the kernel parameter used

`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`:

  Object of class `"matrix"` containing the data matrix used

`ymatrix`:

  Object of class `"output"` containing the response matrix

`fitted`:

  Object of class `"output"` containing the fitted values

`b`:

  Object of class `"numeric"` containing the offset

`lev`:

  Object of class `"vector"` containing the levels of the response (in case of classification)

`scaling`:

  Object of class `"ANY"` containing the scaling information performed on the data

`nclass`:

  Object of class `"numeric"` containing the number of classes (in case of classification)

`alpha`:

  Object of class `"listI"` containing the computes alpha values

`alphaindex`

  Object of class `"list"` containing the indexes for the alphas in various classes (in multi-class problems).

`error`:

  Object of class `"numeric"` containing the training error

`cross`:

  Object of class `"numeric"` containing the cross validation error

`n.action`:

  Object of class `"ANY"` containing the action performed in NA

`nSV`:

  Object of class `"numeric"` containing the number of model parameters
