MIRT Dichotomous module - server — mod_mirt

Computes the response surface of prob_mirt() and the information of info_mirt() on a grid of 50 by 50 abilities from -4 to 4, and plots them as surfaces and contours. The contour plot marks the line where the probability is halfway between the asymptotes and, for the compensatory model, the item_vector(). A discrimination of 0 is rejected with a message in place of the plots.
