In a disease model, I have infected and non infected. I have also for all these collected risk factor (age, gender, educational level, etc.) Using Binary logistic regression, I can calculate the contribution of each factor in causing the disease. Now, I want to calculate the contribution of risk factor combinations (i.e. if age + gender is more important or age + educational level ? ) and also in these combinations, how much is the contribution of each factor. So let us assume that Age + gender scored the highest contribution, but which one contribute more for the occurrence of the disease ?
Thanks a lot
