(2) Choose one for each question.

( Odds Ratio / Rate Ratio / Hazard Ratio ) can be estimated from logistic regression model.

( OR / RR / HR ) can be estimated from Poisson regression model (negative binomial regression model).

( OR / RR / HR ) can be estimated from Cox proportional hazards regression model.
