Ordered models model the probabilities of ending up in each of these
categories, so that is what you can predict. You could use some
arbitrary cut-off, e.g. probability larger than 50% or the category
with the highest probability to assign each observation to one
category, but that basically implies an extra model on top of your
order probit model so I would not do that.
