Method Detail

update

public void update(Lpreg reg)

Sets the SmoothMethod to fixed, then calls the optimize method to determine the optimial fixed smoothing parameter. The SmoothParameter is set to the result.

Specified by:

update in interface SmoothMethod

Specified by:

update in class AbstractSmoothMethod

getLastSmoothParameter

public DblMatrix getLastSmoothParameter()

getSmoothParameter

public DblMatrix getSmoothParameter(Lpreg reg,
                           DblMatrix thisxx)

Since the GCV smoothing parameter is global the specified coordinates are ignored. The update method is **not** called internally.
