Is there any way to perform Ordinal Logistic Regression (OLR) with mlr?

One common implementation is the polr function from the MASS library.

See: https://www.analyticsvidhya.com/blog/2016/02/multinomial-ordinal-logistic-regression/

or

This isn't supported at the moment and won't be added to mlr (though possibly to mlr3 at some point). You can implement your own learner though.

    You can try the mlr3ordinal package. It is still in early stages; contributions are always welcome. – pat-s Oct 02 '19 at 15:30
  • mlr3ordinal sounds like exactly what I have been looking for. I wasn't aware of all these nice extension packages of mlr3. thanks! – krltrl Oct 03 '19 at 15:33
