My dependent variable is in '5 point likert scale' range between -2 to 2. The respondents were made aware of the value assigned to each response. On the other hand, other items (N=23) item were also measured in the same scale. Later, these items resulted in 5 factors using Principal Axis Factoring with Promax rotation. I am using the factor scores as independent variable. The factor scores are in ratio scale. The dependent variable is a single item and well established by literature. Now, I want to perform regression analysis and investigate the impact of these factors on the Solo Variable. Can someone please suggest me which regression analysis will be appropriate in this kind of situation.
