I want to fit logistic regression model for a binary outcome variable to see the impact of other explanatory variable on it. What are selection criteria for selecting variables in the adjusted logistic regression model? What is the basic difference between unadjusted and adjusted logistic regression model?
From what I can tell, there is no difference between unadjusted and adjusted logistic regression; to tell what happens when you add a variable to a logistic regression model, you simply add that variable to the model and see what happens.
You have to be careful about overfitting an colinearity, but that is the basic idea.
