a fitted DRM object (an output from the

Summaries of the fitted DRM object, including the basic information about the fitted DRM, maximum empirical likelihood estimates (MELE) of the DRM parameters, results of the dual empirical likelihood ratio (DELR) test for hypothesis about the DRM parameter beta and some summary statistics of the estimated distribution functions F_k, k = 0, 1, ..., m.
For more detailed but less userfriendly formatted
information about a fitted DRM object, one should directly
check the output from the drmdel
function.
See drmdel
for details.
