Sometimes, though, we are interested in how a risk factor or, Linear models, as their name implies, relates an outcome to a set of predictors of interest using linear assumptions.

Types of Regression Analysis There are several types of regression analysis -- simple, hierarchical, and stepwise -- and the one you choose will depend on the variables in your research. The big difference between these types of regression analysis is the way the variables are entered into the regression equation when analyzing your data.
