Hi,

I'd like to understand what may drive differences in my dependent variable between two sub-populations (wealthy and poor for example) and was thinking of applying something similar to the Blinder-Oaxaca decomposition.

However, my dependent variable is a Likert item and may also be interested in including Likert items among other independent variables (education, income, etc.). I am not sure whether this would be the right approach. Any suggestions would be greatly appreciated.

Thank you
