I think treating income as a categorical variable is a so-so
idea. The only model that would satisfy the ordinal nature of the
categoreis is an ordered probit.

Subject: off topic- prediction model for income estimation
recently i was given a task in a bank to build a predictive model for
income estimation. I wonder if treating the income (dependent variable)
a catagorical variable (grouping income as predefined level) will be
superior than taking income as a continuious interval variable. I m not
which way will be more accurate for prediction.
Would u have any suggestion for me. thx
