From: A new method for determining physician decision thresholds using empiric, uncertain recommendations
A graphical representation of the role of ordinal regression in this method. The four risk levels are arbitrary and chosen for illustrative purposes only. The normal distribution shown at each risk level represents the assumed underlying continuous probability of treatment recommendation that is being assessed using the ordinal scale (Yes, Unsure, No). The two thresholds (αU, αY) are the intercepts derived from ordinal regression analysis of physician responses and form the boundaries between the three response levels.
