A linear combination of predictor variables should be constructed as the linear A linear combination of predictor variables should be constructed as the linear
predictor of the model. predictor of the model. This component is the fixed structural part of the model that
will be used to explain systematic variability between means. If we have Q+1 predictors
in our model, the linear predictor would be:
