16.1  Introduction

In this chapter we will deal with transformations of interval variables. With interval variables we mean variables such as age, income, and number of children, which are measured on an interval or ratio scale. The most obvious transformation of interval variables is to perform a calculation such as addition or multiplication on them. However, we will also see in this chapter that the transformations are not restricted to simple calculations.
