Details

A plot for a cvdglars object is produced.

The plot shows the curve of the cross-validation deviance and the upper and lower standard deviation curves. A vertical dashed red line is used the indetify the value of the \(\gamma\) parameter corresponding to the minimum of the cross-validation deviance.
