ICIsmooth-class: Class '"ICIsmooth"'

In aws: Adaptive Weights Smoothing

Class "ICIsmooth"

Description

The "ICIsmooth" class is used for objects obtained by functions ICIsmooth and ICIcombined.

Objects from the Class

Objects can be created by calls of the form new("ICIsmooth", ...) or by functions ICIsmooth and ICIcombined.
