Hi, I would be very grateful if someone could help me.
I have 2 types of dependent variables: binary (yes/no) and ordinal (5 likert categories). And 4 types predictors: binary (gender), continuous (age), ordinal (education) and interval (income).
I would like to analyse each outcome against the whole set of predictors, preferable with SPSS. I assume that I have to use Binary Logistic Regression for the binary outcome; and Ordinal Logistic Regression for the ordinal outcome. However, I don't know how to deal with the ordinal & interval predictors in both mentioned methods.
I tried to use dummy variables for the ordinal predictor for the Binary Logistic Regression, but not sure if I did it correctly. Also i suspect that the SPSS only consider the dummy variables as categorial without considering the rank.
I read Julie Pallant & Andy Field books, but I still confuse.
Many thanks in advance for your help.
