Multiple regression, the linear predictor
In the previous two chapters we studied regression models where the linear predictor depended on a single explanatory variable, x. In Chapter 3, x was categorical and for a binary variable (Section 3.1) with values g0,g1 we added
to the intercept a, whereas in general, for a variable with k + 1 levels (Section 3.2) we added instead the expression
with dummy variables for all categories except the reference category (xi = 0).
