Independent Variable – Demographic Factors(age, income,gender,marital status,district and education). Technically, both of those likert items are ordinal. For some reason, I forgot what it was, I decided against using this function but implemented something similar in Stan (using ordered_logistic). Note that an assumption of ordinal logistic regression is the distances between two points on the scale are approximately equal. did you figure it out, can you help me? It is hard to judge which variables are important just based on the coefficient values, but just eyeballing them, Q10_3 appears to be the "most important" predictor, assuming it is also significant (i.e., its 95% confidence interval does not include 1). The problem is that the items (dependent variable) are not a single variable. You just have to either dummy-code that variable yourself or, depending on which software procedures you’re using, tell your software that it’s categorical. pls give your expert advice. Dependent Variable – Likert Scale Choosing the correct type of regression depends on the dependent variable, and I’m not sure what your DV is. Thanks for contributing an answer to Cross Validated!
