Basic plot of an edr object

Share:

Description

For an edr object with attributes K <= 2, this function plots the response y versus each new estimate indice with an estimation of the link function. For K = 2, a 3D plot of y versus the two estimate indices is represented. A smooth estimate of the link function is also represented. For K > 2, the pairs function is used.
