Dear professors and colleagues,
I need your help.Actually I have problem related to using categorical variable such as level of education as an independent variable in my model in PLS. for example, for measuring the level of education, I used questionnaire, which has five levels include: secondary, short term vocational, bachelor, master, PhD. It is suggested that to use dummy variables.
Could you please guide me, how can I consider dummy variables for my categorical variable in my model?
Thank you very much
