I have one outcome/dependent variable that can be ordinal or nominal and 3 independent variables. I have learned so far how to perform ordinal and multinomial logistic regression in SPSS between a single independent variable and the outcome variable.
However, I am more interested in examining the effect of the combinations of independent variables on the outcome variable. I could not find an answer online and I am new to regressions.
For example, the first independent variable X1 levels are friends and public, and the second independent variable X2 levels are location and time. So, I want to examine the effect on the outcome var. (what is the coefficient or estimate) in the following four cases that as a mix of X1 and X2 level:
X1= friends and X2= location X1= friends and X2= time X1= public and X2= location X1= public and X2= time
I would really appreciate it if you have any thought of to perform such nested analysis whether ordinal or multinomial regression.
The only way I thought of is to have the different combinations of X1 and X2 merged in one column and have another column for the outcome variable and run the analysis in SPSS but I am not sure if this the right way. If there is no way to do that is SPSS, I would be happy to know to do it in R.
Many thanks in advance.
