The item characteristic curve (ICC) plots the response probability depending on person and item parameter.
For plotting the ICC, the object resulting from MPRM MPRM
or CRSM CRSM
or DRM DRM
is the input for the iccplot
function.
The default argument items="all"
displays ICC curves for all items in the object. With a numeric vector items
, a subset of
items can be selected for which ICC plots are displayed.
