Graphical Tools

  • Olivier Thas
Part of the Springer Series in Statistics book series (SSS)


Most of the graphical tools that have been discussed in Chapter 3 for the one-sample problem can be adapted to the two- and the K-sample problems in a very straightforward way. We focus in this chapter on the QQ and PP plots and on the comparison distribution plots. Just as in Part I we start with defining the population versions of these plots, as these are easier vehicles for explaining how differences between distributions can be interpreted and understood. These graphs are again closely related to the tests discussed in the next chapters.
