Per individual I have 6 percentages (summing to 100 per individual) for 6 different behaviors shown by the individual. I want to perform a multinomial logistic regression on this data in SPSS. However, I can only add 1 variable in the ''Dependent" variable/target box in the multinomial logistic regression analysis. In my dataset each row is an individual, and thus each individual has 6 columns of behaviors with the percentage how much that behavior was observed over a certain time.These percentages are the dependent variables. Happy new year!
Try to rethink the question you need to answer. Multinomial logistic regression would answer a question such as --
- Does the borrower of a loan end up repaying on time, getting an extension, or defaulting?
- Does a respondent prefer broccoli, anchovies, artichokes, or pineapple as a single pizza topping?
- Does an experimental treatment make the patient turn red, blue, or orange?
In these examples, each case fits into one and only one category along the outcome variable. This is not true of your situation.
