In this final chapter we make use of order selection tests in analyzing some actual sets of data. In Section 10.2 tests of linearity are performed on the Babinet data, which were encountered in Section 6.4.2. We also consider the problem of selecting a good model for these data, and perform a test of homoscedasticity. In Section 10.3 order selection tests are used in an analysis of hormone level spectra. Section 10.4 shows how the order selection test can enhance the scatter plots corresponding to a set of multivariate data. Finally, in Section 10.5, the order selection test is used to test whether a multiple regression model has an additive structure.
