If I have a dependent variable having more than two categories (the categories can be ordered) and a few independent variables which are all continuous, then how can I see whether the independent variable affects the dependent variable significantly or not?
I can see that if I run an ordinal logistic regression, then compared to the reference category, a beta coefficient and its significance level is given for each of the other categories of the dependent variable. But my purpose is to comment in an overall manner whether the independent variable affects the dependent variable. For example, whether income(continuous) will affect social status(categorical) significantly. I don't want to find out in comparison to any reference category, I just want to make an overall comment.
If this is possible, then how can I find that overall significance?
