Firstly, I have identified the primary influencing factor A and the secondary influencing factor B. These factors are the influencing factors of customer satisfaction in hotels, for example, A is the room environment, then B is the bed. The influence of these factors on customer satisfaction was investigated through a questionnaire using a three-level Likert scale.
Based on the questionnaire data, I must perform a Bayesian analysis to exclude the less influential factors. How can I do this?
