This chapter shows that explanatory variables can appear in discrete and nonlinear form. These forms give us the opportunity to represent a wide and varied range of possible relationships between the explanatory and dependent variables. The discussions include dummy variables, the quadratic specification, logarithms, and interactions.
Keywords: regression analysis, dummy variables, nonlinear effects, quadratic specification, logarithms, interactions
