oprobpr estimates an ordered dependent variable model on a continuous X variable and an optional set of covariates, then lists and graphs the predicted probabilities from this model against the X variable, holding the covariates constant. Optionally, quadratic or quadratic and cubic terms can be added to the model, as well as interaction terms between X and one or more other covariates. This command has been completely reworked to take advantage of the much-improved version 8 graphics.
