In my research I had a couple of dependent variables which didn't meet the assumptions of normality. Now my supervisor told me that I had to dichotomize these outcome variables and perform logistic regressions on these.
In all the examples of logistic regression on the internet, that I have seen so far, they use a couple of independent variables with just 2 levels. For example gender (1. female 2. male) or smoking (1. yes 2. no)
Now is the case that I have just one independent variable, with 3 levels:
1. No intervention
2. Memory training
3. Walking + Memory training
and I'm looking at the effect on (dichotomized) memory:
1. No recall
Question: Can you perform logistic regression with one independent 3 level variable like you would with a 2 level independent variable?
