Produces a summary of a optimal.cutpoints
object. The following are printed: the call to the optimal.cutpoints()
function; the optimal cutpoint(s) obtained with the method(s) selected;
its/their accuracy measures and the area under ROC curve (AUC) estimates at each categorical covariate level (if the categorical.cov
argument in the optimal.cutpoints()
function is not NULL).
If optimal.cutpoints()
was called with the ci.fit = TRUE
argument, confidence intervals for accuracy measures at the optimal cutpoint are also printed.

an object of class 
... 
further arguments passed to or from other methods. None are used in this method. 
The summary.optimal.cutpoints
function produces a list of summary information for a fitted optimal.cutpoints
object. The result depends on the three arguments, namely, methods
, categorical.cov
and ci.fit
of the optimal.cutpoints()
function used in the optimal cutpoints computing process.
Returns an object of class "summary.optimal.cutpoints" with the same components as the optimal.cutpoints
function (see optimal.cutpoints
) plus:
p.table 
a list with all the numerical information to be shown on the screen.
