Hello,

 

currently I am estimating an ordered probit model with the function polr
(MASS package).

Is there a simple way to obtain values for the prediction of the index
function ($X*\hat{\beta}$)?

 (E..g. in the GLM function there is  the linear.prediction value for this
purpose).

 

If not, is there another function / package where this feature is
implemented?

 

Thank you very much for your answer in advance!

 

Best,

 

Martin
