Diagnostic plots for ordinal logistic regresion

    Hi all, 

    I am trying to figure out what diagnostic plots I could use to evaluate the model fit for an ordinal logistic regression -- using function polr() in the MASS library in R. I have ordered values 0,1,2,3,4 where 0 is better than 1 which is better than 2 and so on.

    I found some papers about ordered multiclass ROC curves, but they are a bit complicated to construct. And since the goal is not pure prediction I was hoping to find some other diagnostic plots to look at.



     Any thoughts?
