Suppose that we wish to determine whether adding a quadratic term in the linear predictor would improve the model. Therefore, we will consider the full model to be 1 y: 1+e-(u+11+,61112) Table 13.4 contains the output from Minitab for this model. Now the linear predictor for the full model can be written as n=X = xll +xzz = n + 311 + [31112
