The demographics I want to analyze are : Economic class (monthly wage), gender, or the residence of the respondents as the exogenous variables. Which I think those variables are Nominal Data (categorical variable) and not ordinal where I can put likert scales on them. Is there any way I could analyze nominal data with PLS-SEM? and what is the needed form of the data? can nominal data be coded to from 1-5 for example? Thank you!
