I have a doubt about hierarchical regression analysis.
My dependent variable is Presenteeism (the act of attending work while sick). Originally that variable has 4 levels (Has it happened to you that you had gone to work despite thinking that you should stay at home because of illness? categories: never, 1 time, 2-5 times, more than 5 times. The first two categories indicate 'no presenteeism', last two categories indicate 'There is presenteeism').
Then, I recoded that variable into 0 and 1 value (0 - no presenteeism, 1 - presenteeism). Maybe I shouldn't have done that?
My main doubt is: can I use hierarchical linear regression when my dependent variable is dichotomous and should it stay as 4-categorical variable or should it be dichotomous?
Or I MUST use logistic regression?
