Variable Transformations

Two-Variable Transformations

Figure 32.20 shows the transformations that are available when you select Two Variable from the Family list. The two-variable transformations are used to compute a new variable from standard arithmetic operations on two variables. The arithmetic is performed for each observation. Equations for these transformations are given in Table 32.8.
