The step - up and step - down methods do not necessarily select the same variables for inclusion in the regression and these differences are magnified when the X variables are themselves intercorrelated. Investigators may sometimes use the step - up method when they wish to define the variables that influence Y more rigorously and to exclude variables that make relatively small contributions to the regression. The step - down method may retain more variables, some of which may make small contributions to the regression, but by retaining them, a better prediction may result.
