Hi, I am trying to run an ordinal probit regression however I am struggling with several things:
1) Does the dependant variable have to be a dummy variable? Currently it has three options = 0 -No, 1- yes in the past, and 2- yes currently. Therefore can I run it like that or does it have to be 0 and 1 only?
2) Do my independent variables (that are categorical) have to be dummy variables? (similar case as for above).
3) If they have to be dummy variables - when I create dummy variables in spss, there are two variables for each case then, do I include them both in the regression?
Also, I have read that because I have several variables that are numerous (scale), I should run Ordinal regression and choose Probit in Options. Does anyone know if that's correct?
Any help would be appreciated as I am feeling lost. Thank you.
P.S. I use spss v22 if that's of any help.
