Probability curve for the 5-category collapsed DCS-D. Graphic representation of the probability of response for each of the 5 categories (0%, 25%, 50%, 75%, 100%). The y axis represents the probability of responding to 1 of these categories (0.0−1.0), and the x axis represents the person measure minus the item measure in logits.
