In the data set faithful, we pair up the eruptions and waiting values in the same observation as (x, y) coordinates. If the box is pushed to one side and some values are far away from the box then it’s a clear indication of outliers. In this paper we investigate ridge regression for the multinomial logit model with symmetric side constraints, which yields parameter estimates that are independent of the reference category.
