My independent variable is Party Identification which I think will be best to create dummy variables for (Conservative, Labour) and then Lib Dem would be the intercept if I'm not mistaken.
The dependent variable is a Likert Scale and I would like to model the effect of party identification on the ordinal variable to look for significant data etc.
If I was to do this in R, can I use polr
, do I have to run a separate model for each dummy variable or can I include them all in same model with the variable I haven't created a dummy variable for being the intercept and how will I interpret the results.
polr
is correct $\endgroup$
