Class "ICIsmooth"

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.

Slots

.Data:

Object of class "list", usually empty.

y:

Object of class "array" containing the original (response) data

dy:

Object of class "numeric" dimension attribute of y

x:

Object of class "numeric" if provided the design points

hmax:

Object of class "numeric" maximum bandwidth
